Hey all,

I'm trying to find out what I assume will be a simple formula but can't figure it out. The idea is this:

There 15 people who are all given the same options (Choice1, Choice2).

What is the probability that all 15 people pick Choice 1
What is the probability of 10 people picking choice 1 and 5 people picking choice 2

Something along those lines. I'll adapt this to more or less people and/or choices, just trying to figure out the right way to go about it.

Thanks in advance!
