Red ball... Red ball (Posted on 2002-10-17) Difficulty: 4 of 5
If you take two balls randomly out of a jar of colored balls, there is a 50% chance that the balls will both be red.

What is the total percentage of red balls in the jar?

The last paragraph and a half shoul not have been boldened. I meant to bolden the word "was" (which had been at that spot, but which has disappeared) and then return to normal type. Apparently I somehow accidently deleted the "was" and the closing formatting brackets. Sorry.
