A bag contains `b` blue balls and `r` red balls. If two balls are drawn at random, the probability of drawing two red balls is five times the probability of drawing two blue balls. Furthermore, the probability of drawing one ball of each color is six times the probability of drawing two blue balls. Then `b+r=9` b. `b r=18` c. `|b-r|=4` d. `b//r=2`
