Find the probability of rolling a 3 first and then an 11 when a pair of dice is rolled twice.

Question

The answers are:

1/18, 1/36, 1/324, 1/162

Answer 1

1/324

there's 2 ways out of 36 possible outcomes to get 3, or 2/36 = 1/18 for getting an initial 3

same with an 11, 2 ways of of 36 outcomes, for another probability of 2/36 = 1/18

multiply 1/18 x 1/18 = 1/324 is the probability of a 3 and then an 11.
