np glad to help :))))

Diameter of D goes all the way to the horizontal location of C center.

Just add the diameters of D and E and radius of C.

6+ 4+ 3/2 = 11.5

If you don't understand anyhting feel free to ask.

I found the one you were looking for, here's the hint

"you can do casework but is there a faster way?"

That's all i'm going to say.

first one too.

We cant see the numbers

no, but anythign divided by 0 is undefined.

it's basically "what's the probability that at least 2 don't roll to be 1?"

So the probability of getting 2 1s is (1/6)^2  and then 1 is total probability so we subtract.

Thus, 1 - 1/36

BUT i think we need to do casework

You see, we have the ones where there's 0 ones, 1 one, ...

then you have to add those too?

idk

yeah 2012-2013

the mods were made mods in 2014 i believe

This is part of a new documentary "Web2.0calc History"

One, display your latex properly, and two, this is a question from AoPS Intro. to counting and probability.

There's no shame in asking for help, besides, if you go anonomus no one except instructors are going to know you.

also what week is this from?

Or actually take a look at this hehehehe

Actually nvm i found out
