Question

What is the probability p(diamonds)?

Answer 1

`1/4`

Explanation:

In a pack of cards there are 52 cards and 13 of them are diamonds.

Therefore the p(diamonds)=`13/52=1/4`

Another way of thinking about it is there are 4 suits in a pack, diamonds, hearts, clubs and spades. The probability of picking one of these suits is `1/4`.
