Based on the experimental probability, predict the number of times that you will roll a 5 if you roll the number cube 300 times.

A. 15
B. 27
C. 48
D. 54.

Answer 2

The experimental probability of rolling a 3 is the frequency of rolling a 3 divided by the total number of rolls:

Experimental probability of rolling a 3 = 11/50 = 0.22

Therefore, the answer is B. 0.22.
