Answer: 0.7
Step-by-step explanation:
Given : A drawer is filled with 9 black shirts, 6 white shirts, and 5 gray shirts.
Total shirts in the drawer = 9+6+5=20
Number of shirts that are not white = 20-6=14
Now, the if one shirt is chosen at random from the drawer. then the probability that it is not a white shirt will be :-
[tex]\text{P(Not white)}=\dfrac{\text{Number of shirts not white}}{\text{Total shirts}}\\\\\=\dfrac{14}{20}=0.7[/tex]
Hence, the required probability = 0.7
