The probability of not rolling a 2 is 5/6, since the probability of rolling a 2 is 1/6.
The answer is 84%. This is because to get a percentage out of 100% you need to have 100 in your total so you multiply 50 *2 to get 100 and since you changed the 50 you also have to change your 42 by the same equation. So 42*2 is 84. Hope this helped please comment if you need clarifying.
