The correct answer is c. 100.
Step-by-step 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 [tex]\frac{8}{24}[/tex].
There are supposed to be 300 trials.
Therefore number of times a diamond card is picked from the pile is given by 300 × [tex]\frac{8}{24}[/tex] = 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.
