Here is me trying:

There are 6 letters, right? All of them are different. You make a tree diagram or a chart.

There are this many: FA, FB, FR, FI, FC, AF, AB, AR, AI, AC, BF, BA, BR, BI, BC, RF, RA, RB, RI, RC, IF, IA, IB, IR, IC, CF, CA, CB, CR, CI.

That is if the same letter cannot be used twice within one permutation. If that can happen, then add 6 to the number.

My answer: 30

The truest thing!

( I feel like this really applies to me!)

HAHA yes, pretty helpful! I didn't even think of any smarter answers!

I don't know because I'm not one of them (and I don't mean to offend anyone here). I think it's just because the AoPS questions are super tricky. I don't know anything about the not learning part, though.

5, because you need 25 times the amount of jelly, so you need 25 times the amount of butter. 

\(1/5 * 25\)=5.

Now the answer isn't incorrect.

What about the heads before the last flip? Gimli could've gotten all tails until the 2009th flip, and then Gimli didn't flip more heads than Legolas (unless he also got all tails).

Every time I check my profile, I see my email, though.

I also know that my email is shown on my profile, so it kind of is public.
