Hi gAr;

Thanks, I did not know about that page.

In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
A number by itself is useful, but it is far more useful to know how accurate or certain that number is.

You're welcome.

I was working on some other way but that did not work.  I will look at the page and try to answer the question.

### Re: Probability problem.

15 numbers are randomly chosen from U(0,1), what is the probability that the sum of last four numbers is greater than 3.5?

Bonus: Can you get a formula for any K instead of 3.5, where K<4 ?

Hi gAr;

Sorry for the delay, I am working on it.

By the last you do mean the 4 largest?
