no its NOT it is ALWAYS 1/6th chance no matter how many times or weeks pass. There are ALWAYS 6 possible outcomes so its ALWAYS 1/6th chance. Or whatever it actually is, the basics stay the same regardless of how complex you make the roll. That is how PURE RANDOM works Previous events do not affect future events. You could get the same items INFINITE number of times, because the chance to do so is ALWAYS 1/6 or whatever number of outcomes there are. Saying it is less likely to happen the more times is happens is BAD MATHS, and would fail you in any Mathematical Test.
