-- The probability of rolling a 22 is zero. That result is impossible, because the sides are labeled with single digits 1 through 6 . Since 22 is not printed anywhere on the cube, it can never come up.
-- The probability of rolling a 2 , however, is 1/6 . (B)
The -probability of rolling something you want is always
(the number of different possible results that you like)
divided by
(the total number of different possible results)
