Question

Given P(A) = 8⁄25 , P(B) = 63⁄100 , and P(A ∪ Bc ) = 19⁄50. Find P(A ∩ Bc ).

Answer 1

P(A and B) = P(A|B) * P(B) = (P(A) / P(A or B)) * P(B)

= ((8/25) / (19/50)) * (63/100)

Answer 2

I know ALL of A = 8/25
and ALL of B = 63/100

I need to figure out the value of the middle shared section and the Universe.



These are my answer choices. Ive have yet to figure out this problem.

a) 0.30
b) 0.29
c) 0.31
d) 0.35
e) 0

Answer 3

Okay, here is another way to think about it.

P(A or B) = (8/25) + (63/100) - x

Solve for x.

Answer 4

so then x= .95
