Question

To play a game, a number cube with sides numbered 1 through 6 is rolled and a fair coin is flipped. Use a table to represent the sample space. What is the probability of flipping a head AND rolling either a 3 or a 5? Round the percent to the nearest tenth.

Answer 1

P(H & 3 or 5) = P(H)P(3 or 5) = 1/2(1/3 = 1/6 = 0.1666... = 16.7% chance

P(H) = 1/2

P(3 or 5) = 2/6 = 1/3
