You place a bet on the number 21 in roulette. the probability of winning is 1 38 , and the company hosting the casino night for a city fundraiser gives the payoff odds as 35:1. what are the odds that the ball will land on the number 21?
1 answer:
1 in 38. Nothing much to say about this problem. There are 38 spaces on the roulette wheel and an every space on a fair wheel has an equal probability of being selected. So you would expect 1/38 = 0.026315789 = 2.6315789% of the time for the number 21 to show up.
