You can become a millionaire! That's what the junk mail said. But then there was the fine print:

If you act before midnight tonight $($and for a mere $$2500$ entry fee$),$ then here are you chances: $0\mathrm{.}18\%$ that you receive $$1,000,000$;

$10\%$ that you break even and get back your entry fee, otherwise you receive nothing at all.

But wait, there's more! For only $$3000$ more, if you don't win the million on your first attempt then

you can choose to play one more time.
