A probability for a certain outcome from a binomial distribution is what is usually referred to as a "binomial probability".

It can be calculated using the formula for the binomial probability distribution function PDF , a. The term n over x is read "n choose x" and is the binomial coefficient: the number of ways we can choose x unordered combinations from a set of n.

As you can see this is simply the number of possible combinations. In some formulations you can see 1-p replaced by q. Note that the above equation is for the probability of observing exactly the specified outcome.

However, often when searching for a binomial probability formula calculator people are actually looking to calculate the cumulative probability of a binomially-distributed random variable: the probability of observing x or less than x events successes, outcomes of interest.

The Binomial CDF formula is simple:. Therefore, the cumulative binomial probability is simply the sum of the probabilities for all events from 0 to x.

Our binomial distribution calculator uses the formula above to calculate the cumulative probability of events less than or equal to x, less than x, greater than or equal to x and greater than x for you.

These are all cumulative binomial probabilities. The inverse function is required when computing the number of trials required to observe a certain number of events, or more, with a certain probability.

For this we use the inverse normal distribution function which provides a good enough approximation. Example 1: Coin flipping.

What is the probability of observing more than 50 heads? Entering 0. Example 2: Dice rolling. If a fair dice is thrown 10 times, what is the probability of throwing at least one six?

This means that while at least one of the conditions within the union must hold true, all conditions can be simultaneously true.

There are two cases for the union of events; the events are either mutually exclusive, or the events are not mutually exclusive.

In the case where the events are mutually exclusive, the calculation of the probability is simpler:.

A basic example of mutually exclusive events would be the rolling of a dice where event A is the probability that an even number is rolled, and event B is the probability that an odd number is rolled.

The calculator above computes the other case, where the events A and B are not mutually exclusive. In this case:. Here the set is represented by the 6 values of the dice, written as:.

The equation is as follows:. As an example, imagine it is Halloween, and two buckets of candy are set outside the house, one containing Snickers, and the other containing Reese's.

Multiple flashing neon signs are placed around the buckets of candy insisting that each trick-or-treater only takes one Snickers OR Reese's but not both!

It is unlikely however, that every child adheres to the flashing neon signs. The normal distribution or Gaussian distribution is a continuous probability distribution that follows the function of:.

Above, along with the calculator, is a diagram of a typical normal distribution curve. The normal distribution is often used to describe and approximate any variable that tends to cluster around the mean.

For example, the heights of male students in a college, the leaf sizes on a tree, the scores of a test, etc. Use the "Normal Distribution" calculator above to determine the probability of an event with a normal distribution lying between two given values i.

P in the diagram above ; for example, the probability of the height of a male student is between 5 and 6 feet in a college. Finding P as shown in the above diagram involves standardizing the two desired values to a z-score by subtracting the given mean and dividing by the standard deviation, as well as using a Z-table to find probabilities for Z.

If for example it is desired to find the probability that a student at a university has a height between 60 inches and 72 inches tall given a mean of 68 inches tall with a standard deviation of 4 inches, 60 and 72 inches would be standardized as such:.

The graph above illustrates the area of interest in the normal distribution. In order to determine the probability represented by the shaded area of the graph, use the standard normal Z-table provided at the bottom of the page.

Note that there are different types of standard normal Z-tables. The table below provides the probability that a statistic is between 0 and Z, where 0 is the mean in the standard normal distribution.

There are also Z-tables that provide the probabilities left or right of Z, both of which can be used to calculate the desired probability by subtracting the relevant values.

For this example, to determine the probability of a value between 0 and 2, find 2 in the first column of the table, since this table by definition provides probabilities between the mean which is 0 in the standard normal distribution and the number of choice, in this case 2.

Note that since the value in question is 2. If instead the value in question were 2. Also note that even though the actual value of interest is -2 on the graph, the table only provides positive values.

Thus, the total number of outcomes would be 7. Total outcomes represent the maximum possible results that can be produced. For example, the total outcomes for a day of the week would be 7.

This is simply because there are 7 days in a week. The formula for calculating probability is very simple. To understand this formula in a better manner, we can go through another example.

Consider that you have a bottle filled with 7 peanuts, 4 pistachios and 6 almonds. What is the probability that when you randomly pick one dry fruit, it would be a peanut?

We need to start by calculating the total outcomes. When you are calculating the probability of multiple events, make sure that the total probability is 1.

To elaborate on this point, we can re-consider the example given above. In the previous step, we calculated the probability of peanuts which was 0.

Similarly, the probability of almonds and pistachios would be given as. In simple terms, conditional probability refers to the occurrence of one event provided that the other has occurred.

Consider that there are two events A and B. Event A occurs before event B. Hence, the conditional probability would be the probability of event B provided that event A has already occurred.

Consider that there is a bad full of 6 red balls and 6 green balls. If a person takes out one red ball, it would be counted as the first event.

After that, if another red ball has been taken out, the probability of this event would depend on the first event. Let us further elaborate on this example.

However, an important condition in this relation is that probability of B should be greater than zero. In other cases, this formula does not hold validity.

When you talk about probability distribution and cumulative probability distribution, they are both terms defining statistical outputs.

There are obviously differences between the two terms. By going through the following points, you would be able to determine the difference between the two terms and understand the implications that each one of them has.

This is how you can determine the probability distribution. Cumulative probability distribution does not involve a specific value but covers a range instead.

We can get more understanding if we re-consider the example mentioned above. In the case of cumulative probability, the calculation is done for a range of values.

If you want to know about the chances of getting one or fewer tails, it is an example of a cumulative probability distribution. When you talk about the difference between theoretical and experimental probability, the theoretical probability is based on expectations.

It is based on estimations and assumptions. On the other hand, the experimental probability is the actual set of results produced after the calculations have been completed.

Experimental probability is not based on assumptions. Further elaboration is explained through the following points. When you talk about A and B, they are taken as two sets.

Let us consider an example so that better understanding is gained. The union of A and B would include all elements that are present in both sets.

This calculation clearly shows that all the elements of set A and B have been included in the union. It is very common to make mistakes when statistical calculations are being performed.

Hence, you should use an online calculator to avoid all kinds of errors. When you talk about the union of two sets, it would include all values that are present in both sets.

In other words, it would be a combination of all values. The probability distribution is related to one value carried by the variable X. The user does not have to relate the variable to any range of values.

Conditional probability requires a particular event to occur before the probability has been calculated.

For instance, if an event A occurs, the probability that event B would occur would be determined. Thanks to your calculator for making it so easy for me to measure probability.
