Please help me with these 2 questions.
1. A party of mens to be seated round a circular table. Find the odds against the event that two particular men sit together.
2. X and Y stand in a ring with 12 other persons. If the arrangement of the 14 persons is at random, find the chance that there are exactly 5 persons between X and Y.
In statistics the odds of an event are defined to be , so the odds of
the event not happening are .
Though I beleive that in some parts of the gamming industry that odds
are defined differently, but UK bookies use them in the sense that statisticians
use them, or at least they did when I was a child.
