Your sock drawer is a mess! You just shove all of your socks in the drawer without worrying about finding matches. Your aunt asks how many pairs of each color you have. You know that you have 32 pairs of socks, or 64 individual socks in four different colors: white, blue, black, and tan. You do not want to count all of your socks, so you randomly pick 20 individual socks and predict the number from your results.
Color of sock
White: 12
Blue: 1
Black: 3
Tan: 4
What is the experimental probability of picking a blue as a decimal?
0.05
