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 (which is 11) divided by the total number of rolls (which is 50).
Experimental probability of rolling a 3 = 11/50 = 0.22
So the answer is B. 0.22.
