two reds fair game

it might be interesting to try to devise other games where the probability of obtaining two red balls (in two picks, without replacement) is 1/2






how many red balls and how many yellow balls would you need?

there is one easy to obtain answer and then lots of difficult ones... that would be hard to find
students could be asked to show that the numbers below do provide for a fair game with P(R,R) = 1/2
