Two dice are thrown. Find the probability that the sum is an even number.

Two dice are thrown simultaneously. What is the probability of getting two numbers whose product is even?

$A$ dice is thrown twice. The probability of getting $4, 5$ or $6$ in the first throw and $1, 2, 3$ or $4$ in the second throw is

$A$ bag contains $6$ red,$4$ white,and $8$ blue balls. If three balls are drawn at random,find the probability that $1$ is red and $2$ are white.

One of the two events must occur. If the chance of one is $\frac{2}{3}$ of the other,then the odds in favour of the other are

$A$ problem in Mathematics is given to three students $A, B$,and $C$. Their respective probabilities of solving the problem are $\frac{1}{2}, \frac{1}{3}$,and $\frac{1}{4}$. What is the probability that the problem is solved?
