Answer
a. 0.11
b. 0.27
c. 0.407
d. 0.344
Work Step by Step
a. P(blood pressure and cholesterol) = 0.11
b. P(blood pressure) = P(blood pressure and no cholesterol) + P(blood pressure and cholesterol) = 0.11 + 0.16 = 0.27
c. P(cholesterol|blood pressure) = P(blood pressure and cholesterol) / P(blood pressure) = 0.11/0.27 = 0.407
d. P(cholesterol) = P(cholesterol and blood pressure) + P(cholesterol and no blood pressure) = 0.11+ 0.21 = 0.32
P(blood pressure|cholesterol) = P(cholesterol and blood pressure) / P(cholesterol) = 0.11/0.32 = 0.344
