If a casino game has an expected win of $5.51 per play with a standard deviation of $13, how do I calculate to SD of the sum of 10 games?

The only thing worse than having to take statistics, is ever thinking about that stupid shit ever again after you've passed. so sorry, I can't be of help.

Good luck ,though.

I took AP Stats this year, but just finished school yesterday, so I don't want to do anymore math.

What do you do for a living?

But also I had the worse stats teacher on earth. Asian that didn't speak hardly any english so understanding her was nearly impossible and I swear she went out of her way to make the exercises extremely uninteresting and tedious.

She would say "this is a factual fact" all the time. It drove me nuts.

When you're able to use the concepts in real life it's cool to have the knowledge, I suppose, but the last thing I'd want to do is someone elses stats homework.
