There are a total of 3 + 8 + 4 = <<3+8+4=15>>15 shirts in the drawer.
The probability that the chosen shirt is not a black shirt is 1 - (probability that it is a black shirt).
The probability that it is a black shirt is 3/15 = 1/5.
Therefore, the probability that it is not a black shirt is 1 - 1/5 = 4/5.
Similarly, the probability that the chosen shirt is not a white shirt is 1 - (probability that it is a white shirt).
The probability that it is a white shirt is 8/15.
Therefore, the probability that it is not a white shirt is 1 - 8/15 = 7/15. Answer: \boxed{\frac{7}{15}}.
A drawer is filled with 3 black shirts, 8 white shirts, and 4 gray shirts. One shirt is chosen at random from the drawer. Find the probability that it is not a black shirt.
