Question

If P(A) = 0.35, P(B) = 0.45 and P(A ∪ B) = 0.65, then find P(B | A)

Answer 1

Answer:

0.728

Step-by-step explanation:

P(A union B)= P(A)+P(B)- P(A intersection B)

putting given values in the above formula

0.65 = 0.35 + 0.45 - P(A intersection B)

So P(A intersection B)= 0.255

P( B/A) = P(A intersection B)÷ P(A)

= 0.255÷ 0.35

= 0.728
