Re: Probability problem.

Hi gAr;

Thanks, I did not know about that page.


In mathematics, you don't understand things. You just get used to them.

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.

You're welcome.

Re: Probability problem.

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 ?

Re: Probability problem.

Hi gAr;

Sorry for the delay, I am working on it.

By the last you do mean the 4 largest?
