Hello. This is probability theory, I htink conditional probability, but I'm not sure.

7 elevator passengers, 10 floors, all indistinct from each other, so there are 15 arrangements that can be denoted (7) - seven get off on one floor, (6, 1) - six get off on one floor and one gets off on another, so on.

What are the individual probabilities of each of the arrnagements?

I believe this has something to do with conditional probability, but I honestly have no idea. Any advice?
