Problem 57E

If the range of X is the set {0,1,2,3,4} and P(X ◊◊x) ◊◊0 2 . , determine the mean and variance of the random variable.

Step-by-Step Solution:

Solution:

Step 1 of 2:

                 Here we have to determine the mean and variance of the random variable.

      Given the range of X = {0,1,2,3,4} and P(X= x) = 0.2.

      Mean

                               

                                = 2

     Variance =

      Where,

                             

                             

    Then,

               Variance =

                             

                               = 2
