Question

The probability that the Cubs win their first game is 1/3. The probability that the Cubs win their second game is 3/7. What is the probability that the Cubs win games?

Answer 1

The correct answer is:

1/7.

Step-by-step explanation:

The two events, the Cubs winning their first game and the Cubs winning their second game, are independent. This is because the Cubs winning their first game does not affect the probability of the Cubs winning their second game.

Since the events are independent, to find the probability that both events occur, multiply the probabilities:

1/3(3/7) = (1*3)/(3*7) = 3/21 = 1/7

Answer 2

We need to multiply these probabilities up. Indeed, we are talking about independent events. Then, the final answer is 1/3 * 3/7=1/7
