Question 382142: A bag contains 6 red marbles, 4 blue marbles, 7 white marbles and 9 yellow marbles. You are asked to draw 5 marbles from the bag without replacement. What is the probability of drawing less than two yellow marbles? Answer by edjones(8007) (Show Source):
You can put this solution on YOUR website! 6+4+7+9=26 marbles in the bag, 9 of which are yellow.
nCr=Combination of n things taken r at a time.
(17C5 + 17C4*9C1)/26C5
=(6188 + 2380*9)/65780
=27608/65780
=.4197 the probability of drawing less than two yellow marbles.
