Trevor's soccer bag holds lots of socks: 4 red, seven green, three white, and two purple. He takes two socks, what is the probability that he will get red and green socks?

Math probability 
Damon,
4+7+3+2 = 16 socks
prob red first = 4/16
prob green second = 7/15
prob that happens = (4*7)/(16*15)
prob green first = 7/16
prob red second = 4/15
so again (4*7)/(16*15)
so in the end 2 * 4 * 7 / (15*16)
= .233
