If $A$ and $B$ are two mutually exclusive events,then $P(A \cup B) = $

One card is drawn randomly from a pack of $52$ cards. The probability that it is a king or a spade is:

The odds in favour of getting a sum that is a multiple of $3$,when a pair of dice is thrown,is:

If $A$ and $B$ are mutually exclusive events,$P(A) = \frac{1}{2}$,$P(A \cup B) = \frac{3}{5}$,and $P(B') = p$,then $p = $ . . . . . . .

Let $A, B,$ and $C$ be events such that $P(A) = P(B) = P(C) = \frac{1}{4}, P(AB) = P(CB) = 0,$ and $P(AC) = \frac{1}{8}.$ Then $P(A \cup B) = \dots$
