Answer:
P(breast cancer) = 0.01
P(no breast cancer ) = 1-0.01 = 0.99
P(positive | breast cancer)= 0.90
P(positive | no breast cancer ) = 0.08
P(breast cancer | positive ) =
Substitute the values :
P(breast cancer | positive ) =
P(breast cancer | positive ) =
Hence the actual probability, if a woman gets a positive test result, that she actually does have breast cancer is 0.531
This is a chord, chord angle problem.
Angle 1 = (50 + 56)/2. This leads to 53 degrees.
