This formula shows that for every value of X in a group of numbers, we have to multiply every value of x by the probability of that number occurs, by doing this we can calculate expected value.

In case if you want to calculate probability and not the expected value, Use this Probability Calculator for accurately finding the probability at run time.

The Expected Value of a random variable always calculated as the center of distribution of the variable. Most importantly this value is the variables long-term average value.

For only finding the center value, the Midpoint Calculator is the best option to try. Expected Value is calculated for single discrete variables, multiple discrete variables, single continuous variables, and multiple continuous variables.

Expected value calculator is used to calculate expected value of all type of variables. Also, remember that none of the probabilities for any set of numbers is greater than 1.

Therefore, there is not a single possibility of having a probability greater than 1 in any event or total of all events.
