It's okay anon, definitely not a big deal anyway. Thanks for understanding though!

I'm rather scared about messing up TeX when posting. I'm not saying you did this but I always thought that if I screwed up, I'd use what you said as an excuse.

Oh anon. That's adorable. Thank you so much for this solution. It's amazing. You did it really similar to how I did but much cuter and better.I wrote pic related just to show my friend quickly how I solved it so my handwriting is rather ugly but anyway. I couldn't really think of a nice scenario for the problem so I just ended up using this club story. Yours is just so so more awesome.
>I'm a bit of a midwit
I won't let you say that. In my eyes you're an amazingwit!
>but I have to admit I looked at their solutions before I finished. It took me a few days.
Thank you for your honesty. I think you did a great job regardless. However I'll say that a few days is a bit too long. For me it took 10 minutes or so but only because I managed to see the counting scenario under it. I'll copy paste what I wrote to my friend
"I thought "We're choosing k people from n people, and then from these k people we're choosing m people. It's almost like we're creating a group of people from these n people such that this group has m special people of some significance"

So another way to count that would be to choose the m special people directly from the n people, and then choose whoever we want from the remaining people."

I'm not usually fast though. I actually shared the problem here because I managed to solve it fast :DDD It could have taken my a few days as well actually.
>This was fun.
Very happy to hear this. We have more problems like this in a combinatorics server. Let me know if you'd like to join.
Again thank you a lot for this image you've created. It's great. Made my day honestly. And good job as well. You've solved it.
