Comments on: What is the probability that everyone who shows up will have a seat if I accept reservations for 25, have 23? http://desdelaxarxa.net/shows/what-is-the-probability-that-everyone-who-shows-up-will-have-a-seat-if-i-accept-reservations-for-25-have-23 Tue, 10 Jan 2012 13:50:26 +0000 http://wordpress.org/?v=2.7 hourly 1 By: zeuz http://desdelaxarxa.net/shows/what-is-the-probability-that-everyone-who-shows-up-will-have-a-seat-if-i-accept-reservations-for-25-have-23/comment-page-1#comment-6523 zeuz Mon, 26 Oct 2009 05:14:59 +0000 http://desdelaxarxa.net/shows/what-is-the-probability-that-everyone-who-shows-up-will-have-a-seat-if-i-accept-reservations-for-25-have-23#comment-6523 np = 25(.9) = 22.5 npq = 2.25 StdDv = sqrt (2.25) = 1.5 Prob (N = 25): Consider Z-score for (25 - 23) / 1.5 = 2 / 1.5 = 1.333. Prob (N = 24): Consider Z-score for (24 - 23) / 1.5 = 1 /1.5 = 0.667 Answer = 100% - Prob (N=25) - Prob (N=24)<br><b>References : </b><br> np = 25(.9) = 22.5
npq = 2.25
StdDv = sqrt (2.25) = 1.5

Prob (N = 25): Consider Z-score for (25 - 23) / 1.5 = 2 / 1.5 = 1.333.
Prob (N = 24): Consider Z-score for (24 - 23) / 1.5 = 1 /1.5 = 0.667

Answer = 100% - Prob (N=25) - Prob (N=24)
