Let $P\left(A\right)=\frac{7}{13}, P\left(B\right)=\frac{9}{13}$ and $P(A\cap B)=\frac{4}{13}$,  Then , $P\left(\frac{\overline{A}}{B}\right)=$

If $P\left(A\right)=\frac{2}{5},P\left(B\right)=\frac{3}{10}$ and $P(A\cap B)=\frac{1}{5}$ then , $P(\overline{A}/\overline{B})P(\overline{B}/\overline{A})$ is equal to 

 If $A$ and $B$ are two events such that  $P\left(A\right)=\frac{1}{2},P\left(B\right)=\frac{1}{3},P\left(\frac{A}{B}\right)=\frac{1}{4}$ then  $P(\overline{A}\cap \overline{B})$ equals

 Let $A$ and $B$ are two events such that $\left(A\right)=\frac{3}{8},P\left(B\right)=\frac{5}{8}$ and $P(A\cup B)=\frac{3}{4}$ Then  $P\left(\frac{A}{B}\right) P\left(\frac{\overline{A}}{B}\right)$ is equals to 

 If $P\left(B\right)=\frac{3}{5},P\left(\frac{A}{B}\right)=\frac{1}{2}$ and $P(A\cup B)=\frac{4}{5}$, then $P(\overline{A} \cup \overline{B})+P(\overline{A}\cup B)=$

 If $P\left(A\right)=0.4, P\left(B\right)=0.8$  and $P\left(\frac{B}{A}\right)=0.6$ then $P(A\cup B)=$

 If  $P\left(B\right)=\frac{3}{5},P\left(\frac{A}{B}\right)=\frac{1}{2}$ and $P(A\cup B)=\frac{4}{5}$ then $P\left(\frac{B}{\overline{A}}\right)=$

Let $A$ and $B$ be two events such that $P\left(A\right)=0.6,P\left(B\right)=0.2$ and $P\left(\frac{A}{B}\right)=0.5$ then $P\left(\frac{\overline{A}}{\overline{B}}\right)$ equals
