Question

If $A$ and $B$ are two events such that $P(B) 
eq 0$ and $P(B) 
eq 1$, then $P(\bar{A} \mid \bar{B})$ is

$P(\bar{A} \mid \bar{B})=\frac{P(\bar{B} \cap \bar{A})}{P(B)}=\frac{1-P(A \cup B)}{P(B)}$

If $A$ and $B$ are two events such that $P(B) \neq 0$ and $P(B) \neq 1$, then $P(\bar{A} \mid \bar{B})$ is
