On the television game show, The Price is Right, there is a segment called \"Showcase

Showdown\". The contestant is asked to spin a wheel which has 20 equally spaced sectors

marked in amounts 5, 10, 15,..., 100. If a pointer on the wheel lands on the sector marked 100,

the contestant wins $1,000. What\'s the probability that the contestant spins the wheel and

wins $1,000?

Solution

Number of items in sample space = 20.

So, probability of getting a 100 = 1/20.

So, the probability that he wins $1000 = probability of getting a 100 = 1/20 = 0.05
