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 denote the number of bars without prize vouchers that she finds and its probability mass function (pmf) is given below:
(i) What sort of distribution does X have? Write down its pmf form.
(ii) Draw the above pmf where 0 ≤ k > k1 > k2 > k3 > k4 ≤ 1.
(iii) How likely is it that the she finds seven or more bar without prize voucher?
(iv) What is the most likely numbers of vouchers that she finds?
