1) Work on problems!

2) Learn how to program well.

3) Learn and use a CAS.

4) Learn an interactive geometry program.

And what should he do in that time?

It will take some time before anyone can solve problems well.

Sort of...
Thats how I made that wild guess, but it doesn't help me to point out the exact

Like everything else it comes eventually. But you already know how to program.

I can do neither.

From programming. it is rather quite easy to visualize but difficult to explain.

Yikes!

Where did you get that formula from?

Thats a brilliant concept

Brilliant and a lot shorter.

but what about the series?

Hmmm, the methods of experimental math never promise the shortest solution! They just promise a solution.



c = 150





To prove for any c it is always 1 / 6 as gAr's method proves.

Hi,

Once we have 3 numbered balls on the table, the sample space is those 3 numbers.
Hence, the probability is 1 / 3!

May be it's more complicated if we are dealing with multisets?

It uses three series to get the answer.

So, how?

bobbym

Amazingly it is the same answer for any n.

I also got something like that
