A card is selected from a pack of $52$ cards. Calculate the probability that the card is an ace of spades.
Let $A$ be the event in which the card drawn is an ace of spades.
Accordingly, $n(A)=1$
$\therefore P(A)=\frac{\text { Number of outcomes favourable to } A}{\text { Total number of possible outcomes }}=\frac{n(A)}{n(S)}=\frac{1}{52}$

What is the probability that when one die is thrown, the number appearing on top is even
One card is drawn from a well shuffled deck of $52$ cards. If each outcome is equally likely, calculate the probability that the card will be a black card (i.e., a club or, a spade)
If $A$ is a sure event, then the value of $P (A$ not ) is
There are two childrens in a family. The probability that both of them are boys is
