Question

A drawer contains 4 white socks, 4 black socks, and 2 green socks. What is the probability that you will select either a black or white sock the first time you reach into the drawer?
A. 2/10

B. 4/10

C. 4/8

D. 8/10

Answer 1

There are a total of 10 socks

From those ten socks there are 4 white and 4 black. A total of 8 white and black socks

We are looking for the probability of selecting a white or black sock out of total socks

So the numbe of white and black socks are 8, and the total is 10

So there is a 8/10 chance to select a white or black sock (This would simplify to 4/5)

So your answer is D
