Even if it doesnt have a normal distribution or the distribution is not known you can find probabilities if the sample size n is large enough.
How to Find the Mean of a Probability Distribution. In other words the mean of the distribution is the expected mean and the variance of the distribution is the expected variance of a very large sample of outcomes from the distribution. The calculator will generate a step by step explanation along with the graphic representation of the data sets and regression line.
The mean of a probability distribution is the average. Add the results from step 3 together. For example consider our probability distribution for the soccer team.
The formula for the mean of a probability distribution is expressed as the aggregate of the products of the value of the random variable and its probability. Suppose n 10 and p 081. PX 1 PX 0 PX 1 025 050 075.
To calculate this we multiply each possible value of the variable by its probability then add the results. Mean of Binomial Distribution. Solution to Example 1.
