Question

Your sock drawer in all mixed up! You

have 7 white socks, 6 black socks, 3
blue socks, and 5 socks with cool
designs (like pineapples, flamingos, and
palm trees). What is the probability
of choosing a pair of white socks?

Answer 1

Explanation:

There are 21 socks in total. Only 7 of them are white.

When you pick your 1st sock, you have a 7/21 chance to get white.

When you pick your 2nd sock, you have a 6/21 chance to get another white, since you already picked a white.

So the probability to get a pair of white socks is 2/21.
