Is this cool with you?

Hi Bobby,

Hi;

I used the one on top of the page here at the forum. For some Firefox settings it does not print correctly.

Hi Bobby,

The code &#928 (with a semicolon immediately after it - I can't include it or the code disappears from my post) prints the symbol about one third larger than MIF's...but it's still the same unclear shape.

This code: Π
MIF's: π

Maybe MIF's can be enlarged to distinguish it from the letter 'n'...but I don't know how to do that.

Letter n: n
MIF's pi: π

I use Google Chrome, on which the two are very similar.

Hi Bobby,

I guess there'd be several ways other than mine to solve that problem: the popular way, your way and gAr's way.

Would you like to post yours? If it's not too advanced, that is. Remember, I can't even spell jeometree.

PS...That "m" in "jeometree" nearly looks like an "r" followed by pi:

m vs. rπ

Hi phrontister;

My solution comes from using experimental methods. I used geogebra for this and all other geometry problems. I have even been experimenting with it to do programming tasks. It is an awesome tool. I will post the whole solution in the Computer math section. Just give me a little time.

New Problem

The argument between A and B has intensified. They are now at the point where they want to fight a duel. Both being mathematicians of sorts they argue for a long time on the rules. A is a poor shooter. He hits his target 35% of the time. B is more accurate, he hits his target 54% of the time. They agree to these rules.

A shoots first 1 time. If B is still alive then B shoots 1 time. Then A shoots 2 times. Next B shoots 3 times, followed by A shooting 5 times. The number of times each shoots is the next Fibonacci number. What are the chances for both duelists?

A says) Of course I am the favorite to kill that B guy.

B says) Not in the long run!

C says) I want B dead too, if A does not get him, I will.

D says)Too bad this is not a 5 way duel!

E says) I agree! Just one thing though how are you each going to carry an infinite number of bullets?

Hi gar;

That is correct. Very good answer, I agree I do not know if those numbers are expressible in known constants.

gAr · 2011-12-09 04:50:21

Hi bobbym,

Okay, thanks!

bobbym · 2011-12-09 05:27:57

Hi gAr;

The person who posed that got a different answer than we did.

gAr · 2011-12-09 05:29:08

Hi,

What did that person get?

bobbym · 2011-12-09 05:34:01

Hi;

I do not remember but it was not right. He got that B has a higher percentage which is clearly wrong.

gAr · 2011-12-09 05:37:25

Okay.
Yes, B would definitely have a lower percentage.

Hi;

How is your schoolwork coming?

gAr · 2011-12-09 05:51:12

It's mostly rote, dull!
I'm stuck in this system.

How's the problem which you were trying?

bobbym · 2011-12-09 05:53:32

Bad, it seems very lucky that I got the right answer. I can not generalize it.

gAr · 2011-12-09 06:09:24

Okay.

I'll take some rest.
See you later.

20 random numbers are drawn from a normal distribution with mean 4 and standard deviation 2. They are labelled a1 to a20. A random number called b is drawn from a normal distribution with mean 3 and standard deviation 3.

What is the chance that b is greater than 10 of the a's?

A says) 1 / 21
B says) About .0307188
C says) .03125
D says) 1/2
E says) It is a complicated expression but one of those answers is right.
