Answer 2

The correct answer is c. 100.

Explanation:

Number of cards in the given pile = 24

Total number of diamond cards in the pile = 8

Probability of picking up a diamond in a draw of card from the pile is given by
`(8)/(24)`.

There are supposed to be 300 trials.

Therefore number of times a diamond card is picked from the pile is given by 300 ×
`(8)/(24)` = 100.

Out of 300 trials to pick a card, about 100 times we can expect to have picked up a diamond card from the pile.
