- As a quick exercise in numeracy, estimate how many lottery tickets are sold
- each draw and how often someone wins the jackpot. This should tell you
- which odds are more likely to be correct. As another exercise, estimate
- the size of the jackpot and the fraction of the sales they are likely to
- give back in the jackpot. Use this information to figure out the
- approximate odds.
