Lets say there are three close friends that have separate profiles on myspace.
For one reason or another they all want to be on a mutual friends top friends list that only has four positions.
Assuming the profile of the mutual friend has 100 friends total; using the myspace randomizer which randomly selects 4 different top friends; what is the probability that all three friends would simultaneously wind up in any order in any of the 4 slots. The fourth slot would be random and not matter.
