  3. A fair 12-sided die is rolled. What is the probability that the roll is a 3 given that the roll is odd? unacademy Let A be the event that a 3 is rolled. Let B be the event that an odd number is rolled. Using the definitions above, this problem can be restated as P(A B). The entire sample space of the 12-sided die is as follows: S 1,2,3, 4, 5,6,7,8,9, 10, 11,12 Because the die is fair, the sample space will be uniform. The event, B, is the following subset of S: A n B is the event that the roll is 3 and is odd. A is a subset of B and An B 3
