Question:
A type of chocolate bar does contain a prize voucher with probability p, 0 ≤ p ≤ 1. Whether or not a bar does contain a prize voucher is independent of other bars. A hungry student buys 8 chocolate bars. Let X denotes the number of bars without prize vouchers that she finds and its probability mass function (pmf)
is given below:
A second student keeps buying chocolate bars until he finds a prize voucher. Let Y denote the number of bars he buys before getting a bar with a prize voucher.
a. What down the probability mass function of Y and verify whether it is pmf or not.
b. If each bar costs 35 takas, what is the expected cost to the second student?
