Two Basic Rules of Probability · Example 5
Refer to the information in. P = tests positive.
(a) Given that a woman develops breast cancer, what is the probability that she tests positive. Find P(P|B) = 1 - P(N|B).
(b) What is the probability that a woman develops breast cancer and tests positive. Find P(B AND P) = P(P|B)P(B).
(c) What is the probability that a woman does not develop breast cancer. Find P(B′) = 1 - P(B).
(d) What is the probability that a woman tests positive for breast cancer. Find P(P) = 1 - P(N).
