You can put this solution on YOUR website! a bag contains 5 red chips, 3 white chips, and 2 blue chips. three chips are selected from the bag without replacement. determine the probability that at least one is red
------------------------
P(at least one) = 1 - P(none)
------------------------
P(none is red) = 5C3/10C3 = (5*4*3)/(10*9*8) = 0.0833
=========================================================
So, P(at least one is red) = 1-0.0833 = 0.9167
=========================================================
