You can initialize a list to [1, 1, 1, 1, 1], and generate 45 random 
integers between 1 and 5, and every time a number is generated, increase the 
Nth number in the list by one.

Not all distinct lists will have the same chance of occurring, e.g. [46, 1, 
1, 1, 1] will be much less likely than [10, 10, 10, 10, 10]. Depending on 
what you need these numbers for, it can be a good thing or a bad thing.
