Check my math please -- I have a 6-digit code...what are the odds that a code will have 4 of the same number in a row at some part of the code?

like 000012 or 100002 or 120000 where the 0's could be any of the same number?

I'm getting 3000 chances, 10 numbers x 100 options x 3 different spots where it can be.

Either way, I get a code 5 times a week...so far this week, I've had the quad-same number twice.

That seems so unlikely.

.01%, the same odds for any 4 specific numbers in sequence -- nm - rollo Oct 16, 05:43

I think you need to use the inclusion-exclusion principle and I'm not doing that math. -- nm - Krusty Oct 16, 05:41
