<PRE><B>Question 546123</B>
You own 23 CDs. You want to randomly arrange 10 of them in a CD rack. What is the probability that the rack ends up in alphabetical order? 
The probability that the CDs are in alphabetical order is 
-----
# of ways to succeed: 1
---
# of random arrangements: 23P10 = 4.1516x10^12
------
P(alphabetical) = 1/(4.1516x10^12)
