Over a period of three months during one year, an airline's rate of involuntarily
denying boarding was 0.85 per 10,000 passengers.
What is the probability that in the next 10,000 passengers,
there will be no one involuntarily denied boarding?
~~~~~~~~~~~~~~~~~
Assume that the rate remains the same in the next 10,000 passengers.
The probability that a passenger will involuntary denyed boarding is P =  = 0.000085.
The probability that a passenger will not involuntary denyed boarding is the complement
P' = 1 - 0.000085 = 0.999915.
The probability that in the next 10,000 passengers, there will be no one involuntarily denied boarding is
 = 0.427399491, or 0.4274 = 42.74% (rounded). ANSWER
Solved.
