You have 4 brown socks, 10 black socks, and 6 gray socks. What is the probability you have chosen a pair of gray socks

3/10 or 0.3

Step-by-step explanation: 4 + 10 + 6 = 20 total socks

6 gray socks/20 total socks = 3/10

30%

Step-by-step explanation:

Probability of gray socks = [# of gray socks / # number of socks] x 100

                                          = [6 / (4 + 10 + 6)] x 100

                                          = [6 / 20] x 100

                                          = 0.3 x 100

                                          = 30%
