Question

In the game of roulette, a steel ball is rolled onto a wheel that contains 18 red, 18 black, and 2 green slots. If the ball is rolled 32 times, find the probability of the following events. A. The ball falls into the green slots 5 or more times.

Answer 1

If I am interpreting your question correctly, on any single spin of the wheel, the ball has 36/38=18/19 chance of not landing on a green space. The chance that it lands in a non-green space for 23 consecutive spins is (18/19)23≈.28836 (i.e. about 28.836% )
