1. Florence Hardware is about to place its monthly order for snow blowers. It bases its estimate of sales next month on the probability distribution given below. Let X= the number of people who want to buy a snow blower. One client can only buy one snow blower. X_i: |0. |1 |2 |3 |4 |5 |6 | P(X_i)|.05|.15|.15|.25|.25|.10 |.05 Assuming that this probability distribution is true, a. What is the mean (or expected) number of people who will want to buy a snow blower next month? b. What is the standard deviation of the number potential buyers? c. If the store stocks four snow blowers, what is the probability it will sell them all?
