Statistics/Math Question [View all]

In my tool bag I have nine black Sharpies and one silver Sharpie.

If I need a black one and I reach into my bag blindly to grab one, what are the odds that I’ll get the silver one every single damn time?

Of course, if I want the silver one, I’ll blindly draw all nine black ones first.
