EVW's answers are also not adequate. This is not her fault. The question as written is very ambiguous. One thing you must always state in the problem whenever you are drawing from a list of numbers, a bunch of urns with balls in them, a deck of cards... is whether or not it is with replacement or not. Please see EVW's post for an explanation of those terms. If you need more please ask.
]]>Hi;
I do not agree.
Why assume x > y? The problem does not state that. And why combinations? x and y are two different variables, so order should count. I think that EVW has the correct two answers for the problem as stated.
Please Mathegocart be more specific which answer, he has 3 different answers, is the one you think is correct.
Where did that little guy go?
That was quite late at night for me, I believe now that EVW's answers are right.

I am at a loss to know which of my answers is correct.

That is precisely the point.
True but I was too lazy to put LATEX on the top. I will now.
Penguins are hard workers so they can not claim they are lazy. So what is it for 3? With replacement or not?
I meant to say without. Penguins are busy animals, surely.

When you're in doubt do both.
bobbym, what do you think of the second answer?
