Poisson is utterly inappropriate for this question. You want the binomial distribution.

Also, you don't mention whether you are playing with an American or a European wheel.

I'll assume an American wheel and you can adjust the probability of individual success if you want a European wheel. The probability of 5 or more is a very long and complex calculation requiring you to calculate the sum of the probability of exactly 5 plus exactly 6, and so on up through exactly 100 (a very tiny number indeed), but the probability of 5 or more is equal to 1 minus the probability of 4 or less, a much simpler calculation.

You can do your own arithmetic.
