b Compute o the variance of x The variance o2 of a probability distribution is used to describe the spread of the values of the random variable The formula for the variance of a probability distribution is given below 0 x f x The mean is needed to calculate the variance We found E x 8 Again the use of a table will help organize the necessary values to find the variance X 4 8 12 x 4 8 4 0 4 x 4 16 Thus the variance is o 0 f x 0 25 0 50 0 25 x f x 16 0 25 0 x f x
