Question

Let X represents the number of homes a real estate agent sells during a given month. Based on previous sales records, she estimates that P(0) = 0.68, P(1) = 0.19, P(2) = 0.09, P(3) = 0.03, P(4) = 0.01, with negligible probability for higher values of x.
a. Explain why it does not make sense to compute the mean of this probability distribution as
(0 + 1 + 2 + 3 + 4)/5 = 2.0.
b. Find the correct mean.
