Challenge:
Santa Clause tells Ruprecht, “This box contains many blue and many red Christmas baubles. There are more blue baubles than red baubles.” Ruprecht draws two baubles from the box, one of which is blue and one of which is red. Santa Clause says, “Interesting! The probability to draw two baubles with different colors is 1/2.”
