   This question arises every time the jackpots reach dizzying heights.   
      
   “What are the odds that at least one ticket will win the Powerball jackpot   
   based on the amount of prize money, sales, or number of tickets sold?”   
      
   There are accurate answers based on three mathematical methods.   
      
   1) If a number of tickets N were sold over several drawings, what is the   
   degree of certainty (commonly known as chance) that at least one ticket will   
   hold the jackpot (the winning combination)?   
      
   2) If a number of tickets N were sold in this particular draw, what is the   
   degree of certainty that at least one ticket will hold the jackpot (the   
   winning combination)?   
      
   3) In the case of rollovers, we know the number of tickets N sold in each   
   drawing. We can calculate the average degree of certainty or chance. Then, we   
   can apply the probability of at least one success in a number of trials   
   (draws).   
      
   I go with method 3, although it leads to a result very close to the   
   calculation of method 1.
