Question

84 people take a driving test.

Answer 1

Answer: The probability that you select a women who passes is 1/2.

First, let's look at the men. 21 of the 84 test takers were men. If the ratio is 5:2 for failing. Then, 15 failed and 6 passes.

Second, let's look at the women. 63 of the test takers were women. If double the number passed, then 42 passed and 21 failed.

The chances that a random person was a women who passes is 42 out of 84 or 1/2.
