A​ 12-sided die is rolled. The set of equally likely outcomes is​ {1,2,3,4,5,6,7,8,9,10,11,12}. Find the probability of rolling a number greater than 8

There are 12 possible outcomes when rolling a 12-sided die, with 4 of them being greater than 8 (9, 10, 11, 12).

So, the probability of rolling a number greater than 8 is 4/12 or 1/3.
