A drawer contains 18 socks: 5 red socks, 10 white socks, and 3 blue socks. Without looking you draw out a sock, what is the probability of NOT getting a red sock?

13/18 which is 72.22% chance of NOT getting a red sock

Step-by-step explanation:

As there are 18 total socks, and 13 of them are NOT red, you have a 13 out of 18 chance, or 13/18, or NOT drawing a red sock. This can be converted to the decimal, 0.7222, or percentage of 0.7222 * 100 = 72.22%
