More Probabilities ...

... but very practical ones this time.


You are invited to go for a screening test for an illness - you have no symptoms.

About 1% of the screened group will have the illness.

The test is 99% accurate at diagnosing people who have the illness.

You get a 'positive' result.

How likely is it that you actually have the illness?


99%?

That's what many people think.
