You can put this solution on YOUR website! A bag contains 3 red chips, 2 blue chips, and 1 white chip. If 2 chips are chosen from the bag(without replacement),
The probability that they are different colors is = 1- P(same color)
= 1 - [3C2 + 2C2]/6C2 = 1 - [3+1]/15 = 1-4/15 = 11/15
--------------------------------------------------------------
A. 11/30 B. 11/15 C. 4/15 D. 2/15 E. None of these.
