In a non-leap year,the probability of getting $53$ Sundays or $53$ Tuesdays or $53$ Thursdays is:

Let $A$ be the event that the absolute difference between two randomly chosen real numbers in the sample space $[0, 60]$ is less than or equal to $a$. If $P(A) = \frac{11}{36}$,then $a$ is equal to $...............$.

If $P(A) = \frac{1}{2}$,$P(B) = \frac{1}{3}$ and $P(A \cap B) = \frac{1}{4}$,then the value of $P(A' \cap B')$ is

Two cards are drawn from a pack of $52$ cards. What is the probability that both cards are red or both cards are kings?

Mr. $A$ has six children and at least one child is a girl. Then,the probability that Mr. $A$ has $3$ boys and $3$ girls is:

The probability that a non-leap year selected at random will have $53$ Sundays is
