If A & B are two events such that p(A)≠0 & P(B)≠1,then P(A′/B)

The correct option is C 1−P(A/B)P(A′/B)=1−P(A/B)=1−P(A∩B)/P(B)

If A & B are two events such that $p (A) \neq 0$ & $P (B) \neq 1, t h e n P (A^{'} / B)$

The correct option is C $1 - P (A / B)$
$P (A^{'} / B) = 1 - P (A / B) = 1 - P (A \cap B) / P (B)$
