Question

Given that P(A) = 0.4, P(B) = 0.90, and P(A and B) = 0.30, determine P(A|B)


0.23
0.75
0.36
0.33

Answer 1

P(A|B)=P(A intersect B) / P(B)
So you have all the numbers needed to calculate P(A|B).

Answer 2

still a little confused

Answer 3

\[P(A|B)=\frac{P(A\cap B)}{P(B)}\]

Answer 4

in your case \(P(A\cap B)=0.3,P(B)=0.9\)

Answer 5

thats not an option up there

Answer 6

P(A|B) = P(A and B)/P(B) = 0.3/0.9 = 1/3

Answer 7

1/3 = .33333333333
