An airline finds that 4 percent of the passengers that make
reservations on a particular flight will not show up. Consequently,
their policy is to sell 100 reserved seats on a plane that has only
98 seats. Find the probability that every person who shows up for
the flight will find a seat available.
What do I know (for example, what is n, pi, and x)? What do I
want to find out? What do I expect the answer to be? How do I go
from what I know to what I want to find? Is the answer consistent
with what I expected?
