A sock drawer has 2 blue pairs, 4 white pairs, 4 black pairs what is the probability you will pick out a black pair

Answer 1

The total number of pairs of socks in the drawer is 2 (blue) + 4 (white) + 4 (black) = 10 pairs.

The probability of picking out a black pair is the number of black pairs divided by the total number of pairs:

4 black pairs / 10 total pairs = 2/5 = 0.4

Therefore, the probability of picking out a black pair is 0.4 or 40%.
