Yang had 10 blue, 6 red, 7 green, and 8 rubber bands in his drawer.He took one out without looking.What is the probability that he took out a brown rubber band? There are 4 answers.Is it 1/31, 1/8, 8/23, or 8/31?

Hello and Welcome to OpenStudy! :) I'm guessing the "8 rubber bands" you mean are the brown ones. either way, probability of something is part over whole (number of brown rubber bands) so ----------------------------- = ? (total number of rubber bands)
