Hi;

There might be a recursion for it...

**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.**

I too thought so.

"Believe nothing, no matter where you read it, or who said it, no matter if I have said it, unless it agrees with your own reason and your own common sense" - Buddha?

Hi gAr;

Oh, not so pleasing to the eyes, is it?!

Summation is much shorter.

I did not know there was another way to write the sum!

What method you used to get the sum?

It is all mixed up in a routine that I wrote to compute the binomial distribution sums. I can use the function but I can no longer unravel what I did. It works but I forget how. I am sorry, back then I did not believe in documenting anything.

New problem:**A point 'P' inside a unit circle is chosen at random.a) A direction is chosen at random at P and a line is drawn from P to the point in the circumference 'Q' in that direction. What is the expected length of the line segment PQ ?b) A direction is chosen at random at the center and a line is drawn from P to the point in the circumference 'Q' in that direction. What is the expected length of the line segment PQ ?**

Hi gAr

I am getting something around for the answer.

Here lies the reader who will never open this book. He is forever dead.

Taking a new step, uttering a new word, is what people fear most. ― Fyodor Dostoyevsky, Crime and Punishment

The knowledge of some things as a function of age is a delta function.
