An airline company knows that over the long run, only 90% of passengers
who reserve
seats show up for their flight.
On a flight with 300 seats, the airline accepts 324 reservations. Assume
the passengers
show up independently.
1. Give the upper bound on the probability that the flight will be
overbooked (more
than 300 people show-up).
2. (Assume that the distribution of weight of US people is normal, with
mean=70Kg
and standard deviation 10Kg. Also, assume the plane is full.
What is the probability that the overall weight of passengers exceeds
21346.4 Kg?
3. Again assuming the plane is full, the probability of each asking N
cups of water is
uniform in N:[1,2,3,4,5,6]. (Nobody asks 0 or more than 6 cups of water)
How many cups of water will they need to load, in order to not run out
of water in
99.85% of their flights?
Please use the probabilities given in the following picture for the
above problems:
