Question 655306: A study of 300 patients found that of 100 alcoholic patients, 87 had elevated cholesterol levels, and of 200 nonalcoholic patients, 43 had elevated cholesterol levels. If a patient is selected at random, find the probability of:\
a. an alcoholic with elevated cholesterol level
b. a nonalcoholic
c. a nonalcoholic with non-elevated cholesterol level Answer by ewatrrr(24785) (Show Source):
Hi,
300 patients found that of 100 alcoholic patients, 87 had elevated cholesterol levels,
and of 200 nonalcoholic patients, 43 had elevated cholesterol levels.
P(A & elevated cholesterol levels) =
P(not A) = 2/3 = %
P(not A & non-elevated cholestrol levels) =
