Cards are selected from a standard deck of 52, the results are recorded in the table. what is the empirical probability of not selecting a heart? express as a fraction

The table have the following results:

Hearts – 7

Diamonds – 4

Clubs – 8

Spades – 5

There is a total of 24

The question is asking for the probability of not selecting a heart.

So we need to add the probabilities of the diamonds, clubs, and spades since these suits are different from hearts.

So = 4 + 8 + 5 = 17

And we have a total of 24 cards

Therefore the probability is 17/24.
