According to the American Heart Association, P(A) = 0.16 and P(B) = 0.29.

Explanation / Answer

A.

P(Both have high cholestrol) = P(A) *P(A) = 0.16 * 0.16 = 0.256 Answer

B.

P(Neither have high cholestrol) = P(B) *P(B) = 0.29 * 0.29 = 0.0841 Answer

C.

P(Both have normal cholestrol cholestrol) = P(B) *P(B) = 0.29 * 0.29 = 0.0841 Answer

D.

P(Atleast one have high cholestrol) = P(A) *P(B) + P(A)*P(A)= 0.16 * 0.29 + 0.16*0.16 = 0.072 Answer
