Answer:
13/20
Step-by-step explanation:
First find the total number of socks
7 + 8 + 3 + 2 = 20
If you want to find the probability of a sock that isn't white, then add all the colored socks together.
8 + 3 + 2 = 13
13/20 chance of selecting a sock that is not white.
If you need a percentage, you can divide the two numbers and multiply the quotient by 100.
