A drawer is filled with 9black shirts, 6white shirts, and 5gray shirts. One shirt is chosen at random from the drawer. Find the probability that it is not a gray shirt.

P (Shirts that are not gray) = 3/4

Step-by-step explanation:

We need to find the total number of shirts

Total = 9black shirts + 6white shirts + 5gray shirts = 20 shirts

We need to find the shirts that are not gray

Shirts that are not gray = shirts that are black and shirts that are white

= 9+6 = 15

P (Shirts that are not gray) = shirts that are not gray / total number of shirts

= 15/20

=3/4
