Since the total number of possibilities is 38, you just need the number of possibilities in each questions divided by 38. For (b) you add up the number of reds and the number of evens and subtract out those which are both (since they are being counted twice). I get 24. For (c) there are 0 possibilities  being green means not red, not black, not even, not odd.

For (b), it helps to be able to count. Of the 18 reds, 8 are even, and 18 + 18  8 = 28. As far as I know, no version of roulette lets you put a single roulette token on the line between Red and Even in order to bet on both, but you can put one token (or more) on each.
