A dodecahedral die(one with 12 sides numbered 1 tob12) is tossed once. Find the following probability. Enter your probability as a fraction. The number on the upward face is not 9
There are 11 equally likely outcomes that are not 9 (the numbers 1-8 and 10-12), out of a total of 12 possible outcomes. Therefore, the probability that the number on the upward face is not 9 is:
11/12
