If A and B are two events such that P(A)= 1 3 , P(B)= 1 2 and P(A B)= 1 6 , then P (A^ / B ) is
Options
- A2 3
- B1 3
- C1 2
- D1 12
Correct answer
A. 2 3
Step-by-step solution
Given P(A)= 1 3 , P(B)= 1 2 and P(A B)= 1 6 aligned P (A^ / B ) &= P (A^ B ) P(B) = P(B)-P(A B) P(B) &= 1 2 - 1 6 1 / 2 = 2 3 aligned
