Generate a random number based on three columns of various probabilities

[javajoe]

I want to generate a random number between 1 and X (where X is a dynamic number of varying length/range) in one of three columns (obviously using RANDBETWEEN) but then controlled by a manually-driven weighting factor assigned to each column I can change at any time.

So far example, if A1 is 70%, B1 is 20%, and C1 is 10%, then generally speaking 70% of the time I want it to give me a random number from 1-5 from column A, 20% of the time I want to return a number between 1-9, and roughly 10% of the time I want it to randomly return a number between 1-3.

70%	20%	10%
1	1	1
2	2	2
3	3	3
4	4
5	5
	6
	7
	8
	9
