Hi,(adsbygoogle = window.adsbygoogle || []).push({});

It has been a long time, and I do not remember how to set up a probability calculation with the following variables -

take a lottery that draws 12 numbers, values 0-9 only, from a hopper that replaces the number after it is drawn, i.e. probability of each number appearing remains constant.

How do I set up an equation to determine probability of, say

2 numbers each appearing 3 times

1 number 3 times and 1 number 4 times, etc..... (can be any two numbers, just want to calculate probability of it happening at all, not for specific digits.)

any help appreciated, thanks
