Question

You are going to roll a fair number cube and spin a spinner with equal sections labeled 1-6. What is the probability that you will roll a number less than 5 and spin an even number?

Answer 1

1/3

Explanation:

P(roll < 5 ∩ even) = P(roll < 5) * P(even)

P(roll < 5) = 4/6 = 2/3

P(even) = 3/6 = 1/2

P(roll < 5 ∩ even) = (2/3) * (1/2) = 1/3
