Hey!
In question 12:
I think the answer is 7%

7% of men with prostate cancer do not have a high level of psa.
And 75% of the men with a high level do not have cancer.
If we want to find the chance of the prostate cancer, in a man with a normal level of psa we should consider the fact that the ones that don’t have a high level of psa , have a normal level of psa, and 7% of them have cancer.

Thanks a lot for the help!! Apparently the answer to Q12 is 0.7% which is kind of weird
