a drawer is filled with 7 black shirts, 5 white shirts, and 10 gray shirts. one shirt is chosen at random from the drawer. find the probability that it is not a gray shirt. write your answer as a fraction in simplest form.
Answer
Explanation:
Step1: Calculate total number of shirts
$7 + 5+10=22$
Step2: Calculate number of non - gray shirts
$7 + 5 = 12$
Step3: Calculate probability of non - gray shirt
The probability $P=\frac{12}{22}=\frac{6}{11}$
Answer:
$\frac{6}{11}$
