A drawer is filled with 3 black shirts,7 white shirts, and12 gray shirts.One shirt is chosen at random from the drawer. Find the probability that it is not a white shirt.Write your answer as a fraction in simplest form.
There are a total of 3 + 7 + 12 = 22 shirts in the drawer.
The probability of choosing a shirt that is not white is the number of non-white shirts divided by the total number of shirts.
There are 3 black shirts and 12 gray shirts, so there are 3 + 12 = 15 non-white shirts.
Therefore, the probability of choosing a shirt that is not white is 15/22, which is already in its simplest form.
So, the probability that it is not a white shirt is 15/22.
