First, contestant chooses one of three outcomes. Then contestant learns that one of other two outcomes is incorrect. Do people switch to another outcome or keep current choice {Monty Hall problem}? Switch, because first guess was only 1/3 correct, but second guess must be 2/3 correct, because contestant now knows that probability of one outcome is zero.
