Yeah. I wanted to do this, but I may need some people's help. Note: this does not require you to do any math, I mean it.

I'm sure everyone is familiar with the show "Deal or No Deal." Well, I know for a fact that the "Bank's price for a case" is just a math formula (how else would they calculate it in 6 seconds after they do the test runs after someone says deal.) Anyway, I want to figure this formula out.

I just need data collectors, that's all. If you're interested, post here. I'll do all of the math figuring the formula out (unless you want to help).

KK, are you sure this is the most suitable forum for that one?

Well, thinking it over again and seeing how popular this thread is, no.

I'm not a member of a math forum, though, and 50,000+ mathematicians have already probably figured it out, so it's not a big deal. It was just some project I wanted to do.

I don't like the show so if it involves me watching it then no I won't help. But I enjoy doing math sometimes, so I'm up for helping with that.

Moved to entertainment considering it deals with the entertainment program Deal or No Deal.

Sounds interesting. I know a few things about math myself, so if you post any problems here I might help.

I don't know anything about that show though.

Orly? I was about to move it back out. Ok.

My plan was to do the following:

A. Make a spreadsheet of all 50 values of the cases

B. Watch the show. As they reveal cases, I mark off the numbers. When the bank deal comes, I write that number down. Now, at this stage, I would need to mark what cases are left, so I might do the markings off in color or do number references (example later). Afterwards, more case openings on the show, more marking off for me. Continue until they go through all of the cases, noting each bank value.

C. Plot it on a spreadsheet. Using some logic and curve fitting, figure out a formula that gives the correct bank value out for any number of cases left (I figure they add the values of the remaining cases in the calculation, so that will be one of the variables).

D. Test the formula. Watch the show. While they dramatize the "bank offer," I crunch some numbers and pop out the value and see if it matches.

I know the general public here can't or isn't willing to do part C, so I was just wanting help with data collection. If you want to help with the math part, again you are more than welcome to.

It's a hyped guessing game, that's all.

They have 50 cases they bring out. The person chooses one, and then starts opening up 5 of those he/she didn't choose. Afterwards, based on the "bank formula", which they dramatize with red lights and giving the show host (Howie Mandell) a fake phone call, they calculate a dollar amount for the case. The player has an option to stop there and "sell" the case (deal) or to go on opening more cases (no deal). If the person says no deal, play goes on, except 4 cases are opened in the second round and even less in the third. This goes on until the person says deal (or, really, pushes a fancy button in the game. It has a fancy cover, too :) . I'll attach it to a nuclear missle for fun :p ), in which the person is asked what cases he/she would have opened if he wanted to continue, and the bank value is given as if normal. Afterwards, he's shown his/her case's value. If a person stops, they get the bank offer. If they go all of the way, they get the case value.

That's all there is too it. Again, it's just a hyped guessing game. Fun, yes, but 100% luck (well, maybe 95% luck and 5% strategy).
