A box has 60 balls, of which 26 are red, 16 are blue, and 18 are yellow. Balls are extracted at random then returned to the box. What is the probability that after performing this test three times exactly two are red and one is yellow?

Best ResponseYou've already chosen the best response.1possible scenarios are R R Y R Y R Y R R probability of each of these is 26/60 * 26/60 * 18 / 60 work this out then multiply it by 3

Best ResponseYou've already chosen the best response.126/60 * 26/60 * 18 / 60 = 13/30 * 13/30 * 3/10 = 507 / 9000

Best ResponseYou've already chosen the best response.1now you need to multiply that by 3 because of the 3 different arrangements of the balls)

Best ResponseYou've already chosen the best response.1169/3000 was correct for each of th 3 scenarios  now you need to multiply that by 3
