Question

What is the probability of choosing a 12-person jury with 7 or 8 women? In other words, calculate P(7 or 8 women).

Answer 1

1/6 chance

Explanation:

There are 12 possible outcomes, so 12 goes in the denominator.

There are 12 vacant spots in the jury, and the outcomes are only favorable if 7 or 8 of them are taken by women.

To find a probability, it is favorable outcomes/total outcomes. In this case, it is a 2/12 probability because there are two favorable outcomes, 7 and 8, and 12 total outcomes. Simplify 2/12 into 1/6, and that's your answer.

Answer 2

THE OTHER ANSWER IS WRONG.

Correct answer: 0.38%.

P(7 or 8 women) = P(7 women) + P(8 women) = 0.234 + 0.146 = 0.38.
