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 white shirt. write your answer as a fraction in simplest form.
Answer
Explanation:
Step1: Calculate total number of shirts
$3 + 8+4=15$
Step2: Calculate number of non - white shirts
$3 + 4 = 7$
Step3: Calculate probability of non - white shirt
The probability $P=\frac{\text{Number of non - white shirts}}{\text{Total number of shirts}}=\frac{7}{15}$
Answer:
$\frac{7}{15}$
