Let $A$ and $B$ are independent events with $\text{P(B)} = \frac{2}{5}, \text{P(A} \cup \text{B)} = \frac{11}{20}$, then $\text{P(A}' | \text{B)}$ is root of the equation}

Let $A$ and $B$ are independent events with $\text{P(B)} = \frac{2}{5}, \text{P(A} \cup \text{B)} = \frac{11}{20}$, then $\text{P(A}' | \text{B)}$ is root of the equation}

For two events $A$ and $B$, $P(A \cup B) = \frac{5}{6}$, $P(A) = \frac{1}{6}$, $P(B) = \frac{2}{3}$, then $A$ and $B$ are
