[h=1]Math question here. Hope someone can help me out.

If a contactlens company has 213696 different prescription combinations possible. And the company sells a total of 3 billion contacts a year. What are the chances in both % and "1:x", that a specific prescription combination is used by someone? (Leaving out other factors, such as probability of a specific range of values customers are likely to have a prescription for.)

Thanks so much in advance!
