1. A large retail company encourages its employees to get customers to apply for the store credit card. Below is the distribution for the number of credit card applications received per employee for an 8-hour shift. X P(X) 0 1 2 3 4 5 0.27 0.28 0.20 0.15 0.08 0.02 a) What is the probability that an employee will get 2 or 3 applications during any given shift? b) What is the probability that an employee will get at most 3 applications during any given shift? c) Find the: (i) Expected value (the mean); and the (ii) Variance and standard deviation for this probability distribution.
