Thanks for this Pyramid:)
how much are you gambling each time?
If you get $4 does that mean that you get $4 plus the amount that you gambled back again?
I hate to nit pick but that is what mathematicians are good at :)
People say I have strange ideas. So, I'd rather not know how the coin will land. If the chance of landing on its side is so small that I have to make a difference less than a cent, I'll round to the nearest cent. I had a think. I guess the normal price is 50c, because if you win, you'll get more money and if you lose, you won't waste much money.
