Question

An airline has a policy of booking as many as 17 persons on an airplane that can seat only 16. (past studies have revealed that only %83 of the booked passengers actually arrive for the flight.) Find the probability that if the airline books 17 persons, not enough seats will be available.

Help please, this is STA.. Thanks ;)

Answer 1

Under what condition(s) are not enough seats available?

What are the chances (the probability) of that happening?

Answer 2

17?

Answer 3

I can get trough out everything after seeing the formula.. but how I got the final answer.?

Answer 4

P(17!)/(17-17)!17!*83^17*0.17^17-17 I got stuck there. please help.

Answer 5

Nop!

Answer 6

Ok!

Answer 7

Yes, It look the same.

Answer 8

I am trying to submit my HW tonight! ;)

Answer 9

Ok, now i got the answer! But How they do it with all the formulas!!

Answer 10

Perhaps I'm under-thinking it, but is it anything more than just 0.83^17?

Answer 11

ohh!

Answer 12

Since there's an 83% chance of each person, and you only care if *all 17* show up.

0.83 x 0.83 x 0.83 x ... x 0.83

Answer 13

Is the answer 4.21%?

Answer 14

Gotcha!! That was faster!!

Answer 15

Almost, 0.0421

Answer 16

Yes. That's the same as 4.21%

Answer 17

I just put 83^17 and I got 00.421 and it was the right answer..

Answer 18

Ok, yes! but they want it as decimal.. jijj!!

Answer 19

Fair enough. Okay, cool.

Answer 20

@bhaskarbabu thanks so much for trying!! =)

Answer 21

@geoffb Cool!!! thank you!!

Answer 22

i thinking far deeper that is y i didn't get it

Answer 23

That was what helped me—I don't know enough about probability calculations to think beyond what I did. ;)

Answer 24

@geoffb may b in your case not inmine

Answer 25

That was an easy way to do it i really appreciate... I just got another question like that and i got it Good!! jejee
