If a fair die is rolled two times, what is the probability that a 3 occurs on at least one roll? Choose the correct choice from the following answers:
A) 25/36
B) 125/216
C) 91/216
D) 11/36
E) 36/216
Questions such as these that talk aboutat leastormaximumorminimumin probability questions should make sure realize that probability of any event (N) to occur = 1- P(Not N)   Thus, the probability of at least 1 roll = 1- Probability of NO 3s = 1- (5/6)(5/6) = 1-25/36 = 11/36.   5/6 is the probability of NOT getting a 3 in any 1 roll with 5 allowed numbers (=1,2,4,5,6) out of a total of 6 possibilities.   11/36 is thus the correct answer.
