Hi gAr;

**I agree with you regarding the satisfaction and importance of actually computing some numbers. I can't tell you how often I see time and money wasted because someone didn't bother to run the numbers.**

Hi gAr;

Until you mentioned it in the post #276, I did not even think about looking for a formula.

I had never done any problems of this type before and did not have any idea of how to solve one, even with a CAS. I have a little idea of how to do them now so I say thanks!

Me neither, thanks to wikipedia and mathworld for the formulas.

But was surprised that I could find no numerical examples anywhere. What will anyone do with the formula if the usage documentation is not there?!

I could not find any book even that would give a decent explanation or example.

New problem:

A certain pattern with a probability of occurrence 'p' has to occur 'k' consecutive times. What is the average number of trials required?

E.g. When 2 dice are thrown, the average number of throws required to get '66' three successive times.
