Two fair dice are tossed. Let $A$ be the event that the first die shows an even number and $B$ be the event that the second die shows an odd number. The two events $A$ and $B$ are

When two dice are thrown simultaneously,what is the probability that the sum of the numbers on the top faces is $5$?

$A$ coin is tossed and a die is thrown. The probability that the outcome will be a head or a number greater than $4$ or both,is

When two dice are thrown simultaneously,what is the probability that at least one of the dice shows a number greater than $3$?

Suppose that a die (with faces marked $1$ to $6$) is loaded in such a manner that for $K = 1, 2, 3, 4, 5, 6$,the probability of the face marked $K$ turning up when the die is tossed is proportional to $K$. The probability of the event that the outcome of a toss of the die will be an even number is equal to

Three coins are tossed once. Find the probability of getting at least $2$ heads.
