How fair is a number from 1 to 100?
Every number has the same 1 in 100 chance. The generator uses your browser's cryptographic random number generator, and removes the tiny bias that a simple method can introduce, so 100 is as likely as 1. Numbers that "look random" are not more likely than ones that look special, like 7, 50 or 100.
