Is this cool with you?

Hi,

Hi;

Okay, then you are ready for the bonus question?

gAr · 2014-01-31 02:54:35

Yeah, sure!

bobbym · 2014-01-31 02:58:47

In the type of problem we are discussing the three largest cards can come in several varieties.

1) All the same 8,8,8.

2) All different 10,7, 5.

3) 2 the same such as 9,9,7.

4) 2 the same such as 8,6,6.

Can you derive general formulas for all 4 types?

Hi;

Have not got to that yet. I am busy correcting the poster on the other forums answer. I have just sent him a message that his method overcounts the number of solutions while yours does not. I have not shown him yours though.

gAr · 2014-01-31 05:15:51

Okay, show both if not convinced.
Is that person a newcomer?

bobbym · 2014-01-31 05:19:10

Hi gAr;

Nope, he is a very strong mathematician. Are you surprised?

gAr · 2014-01-31 05:24:00

Yes, I am!
But not much of a computational type I guess?

bobbym · 2014-01-31 05:26:53

There are few of those around.

Yes, I am!

You should not be, there are few as good as you.

gAr · 2014-01-31 05:33:07

I see.

I'll try to get better!

bobbym · 2014-01-31 05:34:50

Nope, we have to get better!

gAr · 2014-01-31 05:39:55

Yes, we'll get better!

bobbym · 2014-01-31 05:43:23

I probably did not phrase it right. When you said you were surprised, I meant to say you should not be surprised. Even though he is a good mathematician he is not in your class.

gAr · 2014-01-31 06:05:20

No, I had understood what you said there. I was implying that there is still much to know!

As Piet Hein says "Err and err and err again, but less and less and less."

Taking a break, see you later..

bobbym · 2014-01-31 06:13:26

I know that quote, it is a good one. See you later and thanks for coming in.

Hi gAr;

I tried your second formula for (9,8,3)

but could not get it to work. I filled in n3 = 9, n2 = 8 and n1 = 3 with h = 16 ( the number of tens ). Where did I go wrong?

gAr · 2014-01-31 16:27:43

Hi,

Yes, the notations are not clear there.
Try these modified ones.

bobbym · 2014-01-31 21:32:41

Hi gAr;

Looking at them now.

gAr · 2014-01-31 21:41:58

Okay.

bobbym · 2014-01-31 21:52:50

Hi gAr;

I am using 3) for (9,9,7), how would you assign the variables?

gAr · 2014-01-31 22:03:50

Hi,

I am checking again, 3) went wrong I think, like the mistake yesterday.
