23) John’s sock drawer contains 4 pairs of green socks, 7 pairs of black socks, and 7 pairs of red socks. If John reaches into the drawer at random, what are his chances of NOT selecting a pair of green socks?

1. 1/3
2. 7/9
3. 2/5
4. 10/18
5. 3/4

14 of the 18 pairs of socks are not green; the fraction 14/18 can be simplified as 7/9.
