Twenty-five volunteers will wear one of 6 blue, 7 green, 8 yellow, and 4 red aprons during an upcoming food drive. If the aprons are assigned randomly, what is the probability that a volunteer is assigned an apron that is NOT green?

There are 7 green aprons and they are to be assigned randomly to twenty five volunteers. Therefore, the probability of being assigned a green apron is:

Thus, the the probability that a volunteer is assigned an apron that is NOT green is a complementary event and is thus given by:

Therefore, in terms of percentage, the odds of not getting a green apron is 72%.
