If P(A) = 0.6, P(B) = 0.5 and P(B/A) = 0.3 then P(A∩B) will be-
Answer & explanation
Correct answer: option 3
We have P(A) = 0.6, P(B) = 0.5 and P(B/A) = 0.3
We know that P(BIA) = P(A∩B)/ P(A)
⇒ 0.3 = P(A∩B)/ 0.6
⇒ P(A∩B)= 0.6x0.3
⇒ P(A∩B)= 0.18

Correct answer: option 3
We have P(A) = 0.6, P(B) = 0.5 and P(B/A) = 0.3
We know that P(BIA) = P(A∩B)/ P(A)
⇒ 0.3 = P(A∩B)/ 0.6
⇒ P(A∩B)= 0.6x0.3
