antoniya [11.8K]

Answer:

A or D

Step-by-step explanation:

I saw your previous post and saw all of the list and compared it!

I don't think you will type it out in numbers without square root, so that will leave with an option of A,D,E.

I think A is too less, so maybe D?

well which is possible?

Assume that the probability of having sickle cell anemia is 0.15 and the probability of being African-American is 0.45 in a give
irina1246 [14]

Answer:

the probability of having sickle cell anemia given that you are African-American is  P( B|A) =0.288

Step-by-step explanation:

Using Bayes's theorem

P( B|A) = P( A∩B)/P(A)

where P( B|A) = probability of the event B knowing that A happened , P( A∩B) = probability that A and B happen (joint probability of A and B) , P(A) = probability of event A

if B= probability of having sickle cell anemia and A= probability of being African-American

then

P( A∩B) = 0.13

P(A) = 0.45

then

P( B|A) = P( A∩B)/P(A)  = 0.13/0.45 = 0.288

P( B|A) =0.288
