A fascinating little video where Oxford University Maths Professor Marcus du Sautoy explores with Alan Davies. A game show contestant is invited by Monty Hall to choose one of three doors, behind one of which is a good prize (a car) and behind the other two is a bad prize. The contestant is then shown what's behind one of the two remaining doors and is offered a chance to change their selection. Marcus demonstrates that the contestant gains a distinct advantage by changing their selection - something that foxed many mathematicians.
