A slot machine at a hotel is configured so that there is a 1/1400 probability of winning the jackpot on any individual trial. If a guest plays the slot machine 8 times, find the probability of exactly 2 jackpots. If a guest told the hotel manager that she had hit two jackpots in 8 plays of the slot machine, would the manager be surprised?
a. 0.000000510; Yes, the probability of 2 jackpots in 8 plays is extremely small.
b. 0.000000508; Yes, the probability of 2 jackpots in 8 plays is extremely small.
c. 0.0000142; Yes, the probability of 2 jackpots in 8 plays is extremely small.
d. 0.0945; No, hitting 2 jackpots in 8 trials is not so unlikely.
