Answer:
See below
Explanation:
Greater than 10 includes rolls of only 11 and 12 which is 1/6th of the die faces....you should expect 1/6 of the rolls to be greater than 10
15 * 1/6 = 2.5 <==theoretical probability which is within the realm of probability for this small sample (15 rolls)
His experimental probability is 3 rolls out of 15 = 1/5th ...slightly higher than the theoretical prob
