RANDOM VARIABLES AND DISCRETE PROBABILITY DISTRIBUTIONS PROBLEM

                1.   If n = 10 and p = 0.60, then the mean of the binomial distribution is

        2.   If n= 20 and p = 0.70, then the standard deviation of the binomial distribution is

Solution

1.

As

u = mean = np

Then

u =    6   [ANSWER]

2.

As

s = standard deviation = sqrt(np(1-p))

Then

s =    2.049390153   [ANSWER]
