# You don't like to match your socks up after they have been washed and toss them into your dresser. Your dresser drawer has 3 blue socks, 6 black socks, 8 brown socks, and 4 white socks. What is the probability that you will pull out a blue sock?

$\frac{1}{7}$
There are $3$ blue socks and $3 + 6 + 8 + 4$ socks altogether.
This means we have a $\frac{3}{21}$ chance of getting the right colour sock.
$\frac{3}{21} = \frac{1}{7}$
