1% of people have a rare cancer, and there is a test for this cancer which is "90% accurate"; that is:

If you have the cancer there is a 90% chance the test will be positive.

If you don't have the cancer there is a 90% chance the test will be negative.

If you take the test and test positive, what is the approximate probability that you have the cancer?
