We have a binomial experiment with p = 0.4 and n = 2.
(1) Set up the probability distribution by showing all x values and their associated probabilities.
P(0)= (1-0.4)^2 = 0.36
P(1) = 2(0.4)(0.6) = 0.48
P(2) = 0.4^2 = 0.16
(2) Compute the mean, variance, and standard deviation.
mean = np = 2(0.4) =0.8
variance = np(1-p) = 2(0.4)(0.6) = 0.48
sd = sqrt(variance) = sqrt(0.48)
