The probability of getting a sum of $9$ when two dice are thrown is

Suppose $A$ and $B$ are two events such that $P(A \cap B) = \frac{3}{25}$ and $P(B - A) = \frac{8}{25}$. Then, $P(B)$ is equal to

If $A$ and $B$ are two events with $P(A \cup B) = 0.65$ and $P(A \cap B) = 0.15$,then find the value of $P(A^C) + P(B^C)$.

$A$ bag contains $4$ white,$5$ black and $6$ red balls. If a ball is drawn at random,then what is the probability that the drawn ball is either white or red?
