One die and a coin (both unbiased) are tossed simultaneously. The probability of getting $5$ on the top of the die and tail on the coin is

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

Let $A$ and $B$ be two events such that $P(\overline{A \cup B}) = \frac{1}{6}$,$P(A \cap B) = \frac{1}{4}$ and $P(\bar{A}) = \frac{1}{4}$,where $\bar{A}$ stands for the complement of the event $A$. Then the events $A$ and $B$ are

The probability of getting at least one tail in $4$ throws of a coin is

In a single throw of two dice,what is the probability of obtaining an odd number as the sum of the numbers on the two dice?

The probability of obtaining an even prime number on each die,when a pair of dice is rolled,is . . . . . . .
