To find the probability that a randomly chosen shirt is not a black shirt, we first need to determine the total number of shirts. There are 2 black shirts, 7 white shirts, and 11 gray shirts:
Total shirts = 2 (black) + 7 (white) + 11 (gray) = 20 shirts.
Next, we find the number of shirts that are not black. This includes the white and gray shirts:
Non-black shirts = 7 (white) + 11 (gray) = 18 shirts.
Now, we can calculate the probability of choosing a non-black shirt:
Probability(not black) = Number of non-black shirts / Total number of shirts = 18 / 20.
This fraction can be simplified:
18 / 20 = 9 / 10.
Thus, the probability that the chosen shirt is not a black shirt is
