The probability that merchandise stolen from a store will be recovered is 70%. Suppose that a random variable of 8 stores, from which merchandise has been stolen, is chosen, and that the variable x denotes the number of stores recovering their stolen merchandise. Find the mean, mu of the probability distribution for x.
Solution:
mean, μ = np
= (8)(0.7)
