Let X equal the number of "ones" if a fair dice is tossed two independent times by someone out in the hall. If X=x that person gives the player a bowl consisting of 10-3x red chips and 3x white chips. The player then selects one chip at random from the bowl. What is the conditional probability that X=0 given that the chip is red? How does this compare to the prior probability P(X=0)?
