What is the experimental probability of rolling a 3?
A. 0.11
B. 0.22
C. 0.30
D. 0.27.
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.

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.
To find the experimental probability of rolling a 3, we need to divide the frequency of rolling a 3 (which is 11) by the total number of rolls (which is 50). So the experimental probability of rolling a 3 is:
11 / 50 = 0.22
Therefore, the correct answer is B. 0.22.
To find the experimental probability of rolling a 3, you need to divide the frequency of rolling a 3 by the total number of rolls. In this case, the frequency of rolling a 3 is 11, and the total number of rolls is 50.
So, the experimental probability of rolling a 3 is:
11 / 50 = 0.22
Therefore, the answer is B. 0.22.
