Given $P(A \cup B)=0.6$ and $P(A \cap B)=0.2$,the probability that exactly one of the events occurs is:

Let $A$ and $B$ be two independent events of a random experiment. If the probability that both $A$ and $B$ occur is $\frac{1}{6}$ and the probability that neither of them occur is $\frac{1}{3}$,then the probability of occurrence of $A$ is

If $A$ and $B$ are two events of a random experiment,$P(A) = 0.25$,$P(B) = 0.5$ and $P(A \cap B) = 0.15$,then $P(A \cap \bar{B}) = $

If one card is drawn at random from a pack of $52$ cards,what is the probability that it is a king or a queen (in $/13$)?

$A$ die is thrown. Find the probability of the following event: $A$ number more than $6$ will appear.

In a single throw of two dice,the probability of getting a sum of more than $7$ is
