Question

In a pile of cards, there are four hearts, twelve clubs, and eight diamonds. How many times would we expect a diamond to be drawn in 300 trials?

Answer 1

The correct answer is c. 100.

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 .
