What is the probability that the sum of two dice will yield a 9, and then when both are thrown again, their sum will again yield a 9? assume that each die has 8 sides with faces numbered 1 to 8.
Choose the correct choice from the following options: A) 1/64 B) 1/36 C) 1/12 D) 1/6 E) 1/3
Solution -   Rolling dices is an independent event.   The combinations to get 9 are (1,8), (8,1), (2,7), (7,2), (3,6), (6,3), (4,5), (5,4), and total combinations of both dices is 64.   The probability of getting 9 in first attempt is 8/64=1/8.   Probability of getting 9 again in second attempt = (1/8)*(1/8) = 1/64. 1/64NS 1/64
