Re: Simple Probability Q
This is the 'supposed to be' answer:
The probability that both balls will be red is 1/6
The probability that at least one ball is red is 5/6
Therefore the probability that the other ball is red (1/6)/(5/6)=1/5.
This assumes that the balls are picked with equal probability, and that the guy pulling them says that one is red every time that there is at least one red ball.
The answer you probably wanted to see is 1/3, but that's incorrect here. Despite your labeling the thread to the contrary, this isn't really a simple probability question.
