Monty Hall [몬티 홀 문제는]

One of the episodes of the K-drama D.P. (for Deserter Pursuit) is entitled the Monty Hall problem and contains a black-board proof of the (correct) change of probability (from one third to two thirds) for the remaining door… Even though the character states that this is based on statistics (!) and that the reason for the inclusion of the scene remains unclear,  within a progressively darker series, depicting the bullying and hazing taking place within a South Korean army unit and the tragic consequences they have on the victims. (Presumably to demonstrate that the deserter was a brilliant student.)
