Explanation:

Pull one tool out of six, 3 times with replacement.

It gives.3*6 = 18 possibilities

This is equivalent of rolling a number cube with tool names instead of numbers.

Correct option is D.

A. tossing a coin six times

• 2*6 = 12 < 18

B. rolling a number cube six times

• 6*6 = 36 > 18

C. tossing a coin three times

• 2*3 = 6 < 18

D. rolling a number cube three times

• 6*3 = 18
