(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

a airline finds that 5% of people who bought a plane ticket do not show up for the flight. if the airline sells 160 tickets for a flight that has 155 seats, what is the probability that a seat will be available for every person holding a reservation and planning to fly?

2. Relevant equations

central limit theorm

3. The attempt at a solution

since 5% of people dont 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? im really not sure if what i did war right or not, if it isnt, can someone guide me in the right direction?
