Assume 85% of passengers show up, 15% will not. Airline booked 11 people for 10 seats. 1) find probability there are enough seats for the passengers who show up 2) how many are expected to show up?

Probability of passengers to show up=P[s]=.85
Probability of passengers to not show up=P[s]=.15
Airlines booked 10 seats for 11 people.
1) Probability of enough seats for people who show up can be obtained by using normal
approximation to the binomial distribution. This probability is equal...
