I
think I probably know what you mean by "number"  an element of C  but clarification would be helpful.
What do you mean by "random" in this case? Selected according to some distribution from a specified set of primes, perhaps?
About the least ambiguous of the terms you use is "odds", where I think we can safely assume that you are using the colloquial meaning. If not, please clarify.
