So, a probability question for those of you who know the maths...

I'm trying to work out the probability of the rolling the following, if using d10s.

From a pool of 3d10, rolling two 10's.
From a pool of 4d10, rolling three 10's.
From a pool of 5d10, rolling three 10's.
From a pool of 6d10, rolling four 10's.
From a pool of 7d10, rolling four 10's.

and so on...

I, of course, took Formal Logic and Pre-Calc rather than Statistics in college, so I'm not sure how to do the numbers on this. I assume there's a basic formula somewhere.

It does seem a little odd that I didn't take Stats in college, but at the time I thought I wanted to be a Physicist. That lasted until half-way through Pre-Calc, and my ass being thoroughly kicked. The first and only course I dropped and then retook. And retook because I was convinced I could figure it out-- so the second time around I went to tutoring sessions, read extra books on the topic, and bulled my way through. And got a C-. After that, the liberal arts looked really, really good.

Anyway, I should have taken stats if only because I'm a gamer...but well, bad life choices. Like Anthropology as a Major, but live and learn.

Also, The Flaming Lips cover "Borderline"-- here. And that's why I love them.
