Experimental probability is the probability based on the results from an experiment.
To find this, make a fraction of the times the number 3 was rolled over the total times the dice was rolled.

The dice was rolled 7 + 9 + 11 + 6 + 9 + 8 times.
7 + 9 + 11 + 6 + 9 + 8 = 50
The dice was rolled 50 times.
Out of those 50 times, 3 was rolled 11 times.
The fraction is 11/50.

Now make 11/50 a decimal.
To do this, make the denominator 100.
This can be done by multiplying both sides by 2.
11 • 2 = 22
50 • 2 = 100
New fraction: 22/100.
22/100 in decimal form is 0.22.

So the experimental probability of rolling a 3 is 0.22, or 22%.
The answer is B. 0.22
