2.2 Roulette wheel: The game of roulette involves spinning a wheel with 38 slots: 18 red, 18 black, and 2 green. A ball is spun onto the wheel and will eventually land in a slot, where each slot has an equal chance of capturing the ball. a) You watch a roulette wheel spin 8 consecutive times and the ball lands on a red slot each time. What is the probability that the ball will land on a red slot on the next spin? (please round to four decimal places) b) You watch a roulette wheel spin 230 consecutive times and the ball lands on a red slot each time. What is the probability that the ball will land on a red slot on the next spin? (please round to four decimal places)
