The sample space is the set of all possible outcomes of an experiment.
So, I believe the sample space is:
RR, RB, RW, BB, BR, BW, WW, WR, WB
There are 10choose2 = 45 possible draws of two chips. There 5choose2 =10 ways to choose 2 red chips. There are 3choose2 ways=3 to pick 2 blue chips, and 2choose2=1 ways to pick 2 white chips. Probability both chips are the same color is (10+3+1)/45 = 31.1%
The number of ways to draw
