Please answer what is the probability of rolling a 3 on a 6 sided number cube and then NOT rolling a 3 on a 6 sided number cube?

A.  1/6, or 1.67%   B.  5/6, or 83%

Step-by-step explanation:

Because there are 6 sides on the die, and there is only 1 number you are thinking of getting.  That would make the chance 1 out of 6, or 1/6.  

On the other hand, there are 5 numbers on the 6 sided die that you don't want.  this would make the chances of getting the number you don't want a 5/6.  

both equations and proportions are better.
