Question

A drawer contains 12 red socks and 8 black socks. Suppose that you

choose 2 socks at random in the dark. What is the probability that you get a
pair of black socks? *

Answer 1

14/95 or 14.7% to the nearest tenth.

Explanation:

Prob(Black on the first draw) = 8/20 =2/5

Prob(Black on the second draw) = 7/19

Probability you get a pair of black socks = 2/5 * 7/19

= 14 / 95

Answer 2

the probability of getting a black sock is 2/5

Explanation:

because there are 20 socks total and 8 of them are black. That gives you 8/20 which simplifies down to 2/5
