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. write your answer as a fraction in simplest form.
Answer
Answer:
$\frac{15}{19}$
Explanation:
Step1: Calculate total number of shirts
$9 + 6+4=19$
Step2: Calculate number of non - gray shirts
$9 + 6 = 15$
Step3: Calculate probability of non - gray shirt
$\text{Probability}=\frac{\text{Number of non - gray shirts}}{\text{Total number of shirts}}=\frac{15}{19}$
