Mean of the Probability Distribution Calculator to find the mean value. In probability theory and statistics, probability distribution is a statistical function that explains all the possible outcomes and likelihood of a random variable within a particular range. Mean of the probability distribution refers to the central value or an average in the given set. Use our Binomial Distribution Mean Calculator to find mean value by entering X and P(X) values separated by comma.
Total probability of x value must be equal to 1 so that we can find the Binomial Distribution Mean using the above Mean of the Probability Distribution Calculator.
Find the 'n' value and mean of data for X = 2,4,6,3 and Probability of X = 0.1,0.3,0.5,0.1
n = 4
P(X) should be equal to 1
Therefore, P(X) = 0.1 + 0.3 + 0.5 + 0.1
Mean = (2 x 0.1) + (4 x 0.3) + (6 x 0.5) + (3 x 0.1) = 4.7
