Walmark randomly draws 5 different gift vouchers to be given to selected loyal customers each day. For today, they draw the $5 gift voucher. What is the expected number of days until this gift voucher is again drawn? What is the probability that this gift voucher is again drawn exactly 5 days from now? Let X denote a geometric random variable. (Show solutions) O a. E(X) = 10 days, P(X=5) = 0.0819 O b. NONE O c. E(X) = 5 days, P(X=5) = 0.0656 O d. E(X) = 5 days, P(X=5) = 0.0819
