Question 609862
 Three persons A,B and C speak at a function along with five other persons. If the persons speak at random, find the probability that A speaks before B and B speaks before C.
------
# of ways to succeed:
1st 3 speakers 1 way
Last 5 speakers 5! = 120 ways
Total successful orders of speakers: 1*120 = 120
-----
# of random orders of speakers: 8! = 40320
---
P(ABCxxxxx) = 120/40320
