perplexus.info :: Probability : Four balls

Four balls (Posted on 2017-05-19)

There are four balls in a hat: a blue one, a white one, and two red ones. Now I draw simultaneously two balls, look at them, and announce that at least one of them is red.

What is the chance that the other is red as well?

According to you:

".....and 2 would say at least one specific other color"

....and then i ask "...What is the chance that the other
is red as well?
