Use the basic probability principle to solve the following problem. Express each probability as a fraction reduced to lowest terms. 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 9 or a 6. The probability of rolling a 9 or a 6 is (Type an integer or a simplified fraction.) ...
