Experimental probability is calculated by dividing the number of times the event occurred by the total number of trials.

In this case, the number cube landed on 3 ten times out of 30 trials, so the experimental probability of landing on a 3 is:

10/30 or 1/3 (in simplest form)
are you sure
U sure
U sure?
he might be wrong hey bot you sureeeeeeeeeeeeeeeeeee thats right????????????????///
Its very accurate. after all, getting a 3 ten times in a 30 roll trial would be 1/3, or 10/30.
