Re: apples

Hi juantheron;

I am not understanding the question. Is there more?

Taking two apples from the ten is a combinatorics problem not a probability one.


In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.
