Solution

When a card is drawn from a well shuffled deck of $52$ cards, the number of possible outcomes is $52$

Let $A$ be the event ' the card drawn is a diamond ' Clearly the number of elements in set $A$ is $13 .$

Therefore, $P ( A )=\frac{13}{52}=\frac{1}{4}$

i.e. probability of a diamond card $=\frac{1}{4}$
