Solving Math Algorithm Problem with rand(1,1) Function

[sapiental]

Hello

I have to write an algorithm that randomly chooses between A B and C.

I have to use the function (rand(1,1) which gives me a radndom number from the following (0,1,2,3,4,5,6,7,8,9)..

I was thinking of assigning A = 1:3 B = 4:6 C = 7:9

But I run into the problem of the random function giving me a 0.
Could I just write a statement saying that if I get a 0 from the random number generator, to generate anohter number? Would this still remain truly random using the function rand(1,1)?

Any help or suggestions are much appreciated. Thank you!

That should be fine. Unless rand completely sucks ass, there should always be an essentially even chance of getting any of those numbers. Since you'll get an A 3/10 of the time, B 3/10 of the time, and C 3/10 of the time, and pick again 1/10 of the time, you get A 1/3, B 1/3, and C 1/3 of the time
