All right.
00:01
So we have an airline and they know that 5 % of people making reservations on a flight will not show up.
00:07
So the policy is to sell 52 tickets for a flight.
00:10
They can only hold 50 passengers.
00:12
What's the probability that there will be a seat available for every passenger showing up? so this is a binomial probability scenario, a binomial experiment.
00:23
So here are 50 seats here, but we have 52 reservations.
00:28
We have two extra.
00:29
So if there's 51 or 52 people that show up, there will not be a c.
00:36
So we could, one way to do this, and i don't recommend this way, because when i tried this, my calculator actually can process it.
00:43
It gave me some weird value.
00:44
But you want to figure out 52, oops, this is the n.
00:51
52 choose x, pardon me.
00:56
Because we want to get up to 50 people showing up.
01:00
So the different combinations and probabilities of getting 50.
01:04
People showing up...
