The chance of throwing a total of $7$ or $12$ with $2$ dice is:

$A$ problem is given to $3$ students $A, B$ and $C$ whose chances of solving it are $\frac{1}{2}, \frac{1}{3}$ and $\frac{1}{4}$ respectively. Then,the probability of the problem being solved by exactly one of them,if all the three try independently,is

When two dice are thrown,the probability of getting an ordered pair $(x, y)$ such that $x^2+y^2 \leq 25$,where $x$ and $y$ are the numbers that show up on the two dice,is:

When two dice are rolled,what is the probability that the sum of the numbers on the faces is a multiple of $4$?

$A$ card is drawn at random from a well-shuffled pack of $52$ cards. The probability that it is a black card or a face card is

Two dice are thrown three times. What is the probability that the first throw shows $10$,the second throw shows $11$,and the third throw shows $12$?
