Answer 1

The probability of any number is 1/6 = about .18. Which person is closest to that?

Answer 2

1/6 = 0.166666 or about 16% for each possible outcome
How much does each differ from 16% ?
square differences from 16 and add and compare.
Just looking I bet it is Leila.

Answer 3

Which student’s experimental probability is the MOST consistent with the theoretical probability of rolling a six-sided number cube?
