What is the probability that the sum of two dice will yield a 4, and then when both are thrown again, their sum will again yield a 4? assume that each die has 3 sides with faces numbered 1 to 3.  Choose the correct choice from the following:
A) 1/144
B) 1/36
C) 1/9
D) 1/6
E) 1/3
Solution -   Rolling dices is an independent event.   The combinations to get 4 are (1,3), (3,1), (2,2), and total combinations of both dices is 9.   The probability of getting 4 in first attempt is 3/9=1/3.   Probability of getting 4 again in second attempt = (1/3)*(1/3) = 1/9. ANS 1/9
