Question

According to the cdc men who smoke are about 20 times

Answer 1

Answer:

Question says that it is 23 times more likely for a smoker to develop lung cancer than a non-smoker, and 21.6% men in U.S smoke. We are required to find probability that a person is a smoker, if he develops cancer.

I believe the question is related to Conditional probability but I am not sure how to right 23 times more likely in terms of probability. Any help will be appreciated. Thank you!

So far I have defined two events:

A: Man has cancer.

B: Man Smokes.

We have P(B), and I believe we need to find P(B|A), I am stuck and don't know how to move forward.

Thank you!
