Good observation. I think can all agree that there is no such thing as "weak crabs."

Dunno. Since he's not allowed any protection, one of our fellow RHPers may be sporting crustacea to make anything Bayesian methods can handle look weak.

Correct! there are W^3 circles on a 2D Plane. How about Elipses?

W^5: centre point (2df) + length&direction of major axis (2df) + length of minor axis (1df)

It can be done using standard mathematical functions . (b) is reducible to the form of (a) and ( a) is integrable in terms of standard functions.

Well, this is the first time I had a run at it. I think it's a pretty good puzzle. Answer: the German had the fish. I'd put in the whole table that I came up with, but that would take the fun out of it for anyone else who wanted to work it out.

It's actually Vedic Mathematics, an ancient gem of India:

Multiply the unit's place of the multiplicand by that of the multiplier:
i.e. 9*1=9.

Prefix a 0 to that product 9 (There is a reason behind this, which you need not bother now)

Now, since 91 (multiplier) is 9 less than 100 (100 is considered as a base in vedic maths), you subtract the same deficit (9) from 99 (the multiplier), which is: 99-9=90.

There's your answer: 9009!

You choose a door at random

He says you may change your choice to un opened door or stay with your original choice.
should you stay with your choice, change door or dosent it matter?[/b]
easy:
1/3 chance of it being in the one you chose, call it A.
2/3 chance of it being in B or C.
He opens up B, empty
therefore there is now a 2/3 chance of it being in C.

Definately switch!!!
1/3 chance by staying with it, 2/3 chance by switching.
