A die is thrown, find the probability of following events: A number less than or equal to one will appear,
The sample space of the given experiment is given by
$S=\{1,2,3,4,5,6\}$
Let $C$ be the event of the occurrence of a number less than or equal to one.
Accordingly, $C\{1\}$
$\therefore P(C)=\frac{\text { Number of outcomes favourable to } C}{\text { Total number of possible outcomes }}=\frac{n(C)}{n(S)}=\frac{1}{6}$
Three coins are tossed once. Find the probability of getting no tails.
Two dices are rolled. If both dices have six faces numbered $1,2,3,5,7$ and $11,$ then the probability that the sum of the numbers on the top faces is less than or equal to $8$ is
