Answer: No, I do not believe that there is enough convincing evidence to proof that he can control the dice.
When you roll a die, there is a 1/6 probability that you will roll a 6. If you multiply 50 by (1/6) you would expect your friend to roll at least 8 sixes.

The length of the sides would be 11.
11 * 11 = 121
Hope this helps!
