Q. If A and B are any two events such that P (A) + P (B) − P (A and B) = P (A), then (A) P (B|A) = 1 (B) P (A|B) = 1 (C) P (B|A) = 0 (D) P (A|B) = 0

Q. If $P\left(A\right)=\frac{1}{2},P\left(B\right)=0$,
then $P\left(A|B\right)$ is

Q. If $P\left(A\right)=\frac{1}{2}$, $P\left(B\right)=0$, then $P\left(A|B\right)$ is

Q. Let $A$ and $B$ be two events such that $P(A\cup B)=P\left(A\right)+P\left(B\right)-P\left(A\right)P\left(B\right)$. If $0<P\left(A\right)<1$ and $0<P\left(B\right)<1$, then $P(A\cup B{)}^{\prime }$ is equal to

Q. Let A and B be two events such that $P(A\cup B)=P(A\cap B)$. Then,
Statement 1: $P(A\cap \overline{B})=P(\overline{A}\cap B)=0$
Statement 2: If $P\left(A\right)+P\left(B\right)=1$.
