(b) Find the probability that he has to throw the dice exactly twice to get the five.
(c) Calculate the probability that he will have the throw the dice more than twice to get a five.
Answer:
Step-by-step explanation:

(d) Prob(Not M, Not M , M)
= 25/26 * 25*26 * 1/26
= 625/17576
or 0.036 to nearest thousand
(e) Prob(Not M, Not M, M) without replacement
= 25/26*24/25*/1/24
= 1/26
or 0.038 to nearest thousandth.
2(a)
1/6.
(b)
5/6 * 1/6
= 5/36.
(c)
