Oh, that's bad!
Is it raining heavily over there?

Re: What do you think?

Rained for a whole week! This a desert and it gets a lot of rain. Where does the water go?

Re: What do you think?

That's strange!
Is it the first time happening like that?

Re: What do you think?

No, it has happened before. The whole state is freaky like that. If you drive a little bit up north it is like you are on another planet.

Oh, I see!
I may need to go out.
See you again sometime...

Thanks!

A twitter feed from geogebra linked to this:
http://www.quantimegroup.com/solutions/ … edean.html - A java program for exploring solids, haven't tried it yet...
See you later!

Thanks for that. I have heard about it but have not tried it either.

Re: What do you think?

A new problem:

What is the area of the largest triangle that can fit inside of a square with sides s? What type of triangle is it?

Did you check my answer in the other thread?

Hi;

Still working on it. It does agree with simulations.

Re: What do you think?

Hi;

New problem:

There are red balls and blue blue balls in an urn. The number of red balls is either 7, 9, 11,13, or 15. If two balls are randomly chosen  from the urn,  the probability they are different colors is 1 / 2. How many red balls are in the urn?

A says) Kaboobly doo! All those answers are correct! If I had 9 red balls then 9 blue balls would give the required probability. Same argument holds for all the others.

B says) Nope!

C says) I have to agree with A. B is kaboobly doo.

D says) This is why I hate probability, lots of dumb questions that fry your brain!

B says) I am hungry so keep thinking D.

A says) You are right D,  B is serious, his cannibalistic tendencies are well documented.

E says) B is not a cannibal, documented or not. He is just a lousy mathematician. I do not know how he got the right answer. I suspect he is lucky.

A says) Well I am a great mathematician and I have the letters after my name to prove it. B's answers and his general way of working are nothing but trendy tripe! It sickens me to see these computational yoyo's using excremental math.

E says) You mean experimental math, or maybe you don't?

Too be continued...

Re: What do you think?

It is very unusual because lots of people would agree with A on this one. The correct answer is so counterintuitive!

Re: What do you think?

Yes, I too thought equal number of red and blue balls would give the required probability!

Re: What do you think?

It is very strange. If someone asked you to stock the urns so that there is a fifty-fifty chance for each player and you put in 15 and 21, people would think you were nuts! When I first solved the problem I was afraid to write down the answer!

Not bad for now, I guess.
