Question 1017429: A 12-sided die, numbered 1 to 12, is rolled. Find the probability that the roll results is an even number or a number greater than 4 Answer by fractalier(6550) (Show Source):
You can put this solution on YOUR website! Call P(A) = P(even) = 6/12 = 1/2
Call P(B) = P(>4) = 8/12 = 2/3
P(A or B) = P(A) + P(B) - P(A and B) = 1/2 + 2/3 - 4/12 = 5/6
