The relative frequency of selecting a diamond from 40 trials of selecting a random card is 30%.

<h3>What is relative frequency?</h3>

The relative frequency of an event is the ratio of total number of favorable or desired outcome to the total number of trails done.

Given information-

The card is selected random from the deck of cards.

Total number of trails is 40.

It is known that the total number of diamond card in a standard deck of card is 11. There is total 40 trials is done in which a random card is selected.

As the relative frequency is the ratio of total number of diamonds to the total number of trials done. Thus,

f_r=\dfrac{11}{40}\\f_r=0.3

In the percentage from,

f_r={0.3}\times100\\f_r=30

Thus the relative frequency of selecting a diamond from 40 trials of selecting a random card is 30%.
