Rest them fingers now, no excessive typing. GOOD LUCK

Oh do not worry. I'm getting a thai massage with a concentration in the hands the night before.

Is that the one where they slap you in the face for $350?

ok, well, take 6 rolls.

the expected number of 7s is 1.

But if you offer over/under on number of 7s in 6 rolls I am gonna crush you by taking over 1 for even money.



Isnt the under 1 about 34%, exactly 1 about 40% and over one 26%? Wouldnt I prefer to be on the under?

Yes, here I was assuming it was "one or more." But you are correct.

Even if the o/u here is exactly one, it wouldn't be fair

Good things happening in this thread. I have to say it is really frustrating reading the posts going back and forth between SOOPOO and Ahigh with such acrimony, when I think it's really a communication issue about what is being claimed and a fair way to test that claim of bias...especially since I know they've met in person and claim to not hate each other!

Hopefully with the nickolay411 challenge we can move forward with some testable hypotheses. I only hope that if there are further challenges after this one, the number of rolls is increased. No need to do them all at once, 10 100-roll sessions spaced out over a few days would be a good test. I would probably put up some money on that one.

Indeed.

For 200 rolls the over/under 33 wouldn't be fair either :

Under 33 -> 44.5%
Over 33 -> 48.0%
Exactly 33 -> 7.5%

It's a good point you make.

Can I assume that before the first roll, there will be an agreement whether he will roll 100 or 200 times ?

also.. in your example, 16.67 out of 100. 100 is not evenly divisible by 6. So in that case making the over/under 16.67 is the equivalent of making it 16.5

Just like in one roll, the mean 7s is 0.167 but if you make that the over/under, under is going to dominate.



That is why i SPECIFICALLY said for any number divisible by 6, so 100 is not in play.
