A drawer is filled with
9

black shirts,
6

white shirts, and
4

gray shirts.
One shirt is chosen at random from the drawer. Find the probability that it is not a gray shirt.

Respuesta :

15/19 is the answer because if you add all the t-shirts you get 19. Subtract 4 and you get 15 that's the number of t-shirts you would have a possibility of drawing that is not grey.   The answer is 15/19
