  1. I’m glad our pointy-headed academicians are working (on the taxpayer dime no doubt) on such important ground-breaking life-altering saving the world endeavors like this.

  3. Dr.Tar, I’m sure a casino would offer you that.
    The amount of times you would have to flip to come out a winner would be staggering.
    Of course many other variables in play.

    Will the sub in another flipper like they do dealers?

    Try it yourself by flipping a coin 10 times.

    Blackjack has similar odds if played correctly with a single deck, dealer stands on soft 17, etc.
    Thing is, the house always wins in the long run.

  5. RadioMan, I just flipped a 1923 Peace Silver Dollar 10 times.
    1) Start with Heads, result: Tails
    2) Tails/Tails
    3) Tails/Heads
    4) Heads/Tails
    5) Heads/Heads
    6) Heads/Tails
    7) Tails/Tails
    8) Tails/Heads
    9) Heads/Tails
    10) Tails/Heads

    3 out of 10 is far away from 50.8%
