The Attempt at a Solution
since 5% of people don't show and the airline sells 160 seats:
160x0.05= 8
so of the 160 that buy a ticket 8 people will not show up:
160-8= 152
since there are 155 seats and 152 show up for the flight:
152/155= 0.9806
is this right? I am really not sure if what i did war right or not, if it isnt, can someone guide me in the right direction?
