If $P(A)=0.59, P(B)=0.30$ and $P(A \cap B)=0.21$,then $P(A^{\prime} \cap B^{\prime})$ is equal to

An integer is chosen at random and squared. The probability that the last digit of the square is $1$ or $5$ is

Two persons $A$ and $B$ throw three unbiased dice one after the other. If $A$ gets a sum of $13$,then the probability that $B$ gets a higher sum is:

Two fair dice are rolled. The probability of the sum of digits on their faces being greater than or equal to $10$ is

Three coins are tossed once. Find the probability of getting $3$ tails.

If $A$ and $B$ are events of a sample space such that $P(A \cup B) = \frac{3}{4}$, $P(A \cap B) = \frac{1}{4}$, and $P(\bar{A}) = \frac{2}{3}$, then $P(\bar{A} \cap B)$ is
