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, $n(A)=1$
$\therefore P(A)=\frac{\text { Number of outcomes favourable to } A}{\text { Total number of possible outcomes }}=\frac{n(A)}{n(S)}=\frac{1}{52}$
