Asked by SYDNEY

A pair of fair 6-sided dice is rolled. What is the probability that a 3 is rolled if it is known that the sum of the numbers landing uppermost is less than or equal to 6?

two ways to get a sum of 3 either 12 or 21

our possible outcomes, sum ≤ 6 :
11, 12, 13, 14, 15
21, 22, 23, 24
31,32, 33,
41, 42
51
15 of them

prob(your event) = 2/15
