Quick Question For Those Good at Die Probability

[Paul_Klein]

Just a really quick question:

What are the odds of rolling a Natural 1 and then following it up with a d20 roll of 1 through 10?

Thanks!

1/40 = 2.5%

To be a bit more verbose...

Chance to get the natural 1 is, of course, 1/20.

Chance to get a 1 through 10 is 1/2.

Chance to get one, and then the other is the product of the probabilities of each individual event. 1/20 * 1/2 = 1/40.
