10 Black marbles @ 1 oz. ea. = Ink jar
10 White marbles @ 1 oz ea. = Water Jar
Remove one black marble from Ink Jar and add it to the Water Jar
Water Jar now has 11 marbles @ 10 to 1 ratio (white to black)
Reach in (blind) and remove one random marble (odds are 10 to 1 that it will be a white marble) and put that marble in the Ink Jar.

The Vegas line says: Bet with Mr. Carlton - 9 white one black / 9 black one white ... but people do win the lottery occasionally ..so....)
