Okay, so here's a quick and easy math question for the didn't plan on it but Mr. K asked for it math quizzine series:
When rolling a 20-sided die, what are the odds of rolling a two-digit number?
Bonus question: When rolling a pair of 20-sided dice, what are the odds of rolling two one-digit numbers?
Have fun!

doesn't it matter what the dice is numbered?
If the dice is numbered 1-5 four times, then the odds are "nil".
If the dice is numbered 11-30, or 51-70, the odds are 1:1.
hmmm.

My apologies LB... one was to assume a standard 20-sided die with numbers from 1 through 20.

Ooh, thanks!
Grend31 is a mathematical genius. I have checked over his work, and I approve. You may all exhale.
