I have to do a worksheet for my AP stats class and I was wondering if anyone could help me get started on the first question. I do not want an answer, just help please =)
Promt: For previous records on Mudlark Airlines, about 15% of people who had tickets for the flight did not take the light. There are 120 seats on the plane. (it also discusses overbooking in the previous paragraph)
Question: how many tickets should mudlark Airlines sell for this flight?
~I know that n=20 and p=.15
