  What is the general equation to calculate the expected value that

  In other words, calculate the expected value of a $1 ticket given
  a prize of $P, where n numbers (6 in this case) are chosen out of
  a possible N numbers (50 in this case) and there are m people
  playing.

  Assume that everyone picks randomly or that you pick your ticket
  randomly (does it matter?).
