**New problem:**

**B is walking along the street in Vegas and runs into "Mad Archil."He tries to avoid him but Archil is faster and catches up. "Hi, living legend, care to make a wager?" Now everyone knows about Mad Archil.The guy is capable of winning or losing millions of dollars but mostly losing them. His last escapade resulted in him beating a large casino out of 40 million! B knows that Archil is a horrible gambler but also knows that he can not cover the bets Mad Archil likes to make. Mad Archil assures him that he is almost broke and has only 100 dollars in his pocket. He says let's flip a coin. If it is heads then you pay me 1 / 2 of what I have in my pocket, if not I pay you half.B immediately accepts the wager and they play. Mad Archil keeps the score of the coin tosses and amazingly by the 70th throw of the coin, Mad Archil is totally wiped out. He accuses B of using a loaded coin until he notices that there were exactly 35 heads and 35 tails! He stares in disbelief as B walks away with the dough.**

**A says) Hard to believe the story is true. 35 heads and 35 tails should have made it an even bet. I do not see how he lost all his money. B is obviously lying.**

**B says) Nope, that is what happened.**

**C says) Clearly a 50 - 50 proposition. Sadly B, you wasted your time.**

**D says) Yep, A is right. No advantage either way.**

**E says) What do you have in your pocket A? Care to make me the same wager Archil did?**

**The question is did B make a good bet?**

Wait, so, do they give 50 dollars each time or ...?

Hi anonimnystefy;

No, half of what is left in his pocket. If he loses the first bet he loses 50. If he now loses the second toss he loses 25. Or he wins the first toss, he now has 150, he loses the second toss he now has 75.

Hi ElainaVW;

The correct phrase is RIPOSTP! But you are at least correct with the reference. I see you now have that book?

Your brother was kind enough to loan me your copy. Interesting comments in the glossings?

What happens if he has an odd number of dollars in his pocket?

He wins half of it or loses half of it. The arithmetic was done after each toss using a TI - 92. at the end they decided on the rounding.

Yes! That was kind of him.

Do you have a proof or something like that?

Is Gardner related to Lewis Carrol?

I never heard that. I tend to doubt it.
