Title: Twenty marbles are used to spell a word—9 blue ones, 5 red ones Post by: woot woot on Sep 23, 2014 Twenty marbles are used to spell a word—9 blue ones, 5 red ones, 3 yellow ones and 3 green ones. If two marbles are drawn from the set of twenty marbles at random in succession and without replacement, what is the probability (as a reduced fraction) of choosing a marble other than yellow each time?
