$2$ dice are thrown. Find the probability of getting a sum greater than $10$.

$A$ husband and wife appear in an interview for $2$ vacancies in the same post. The probability of the husband's selection is $1/7$ and that of the wife's is $1/5$. What is the probability that at least one of them will be selected?

$A$ three-digit number is formed by using the digits $1, 2, 3,$ and $4$. The probability that the number is divisible by $3$ is:

If $P(A) = 2/3$,$P(B) = 1/2$ and $P(A \cup B) = 5/6$,then events $A$ and $B$ are

The probability of a sure event is

$A$ bag $X$ contains $2$ white and $3$ black balls and another bag $Y$ contains $4$ white and $2$ black balls. One bag is selected at random and a ball is drawn from it. Then the probability for the ball chosen to be white is
