In search of a new car, the player picks a door, say 1. The game host then opens one of the other doors, say 3, to reveal a goat and offers to let the player pick door 2 instead of door 1. The Monty Hall problem is a probability puzzle loosely based on the American television game show Let's Make a Deal and named after the show's original host, Monty Hall . The problem, also called the Monty Hall paradox , is a veridical paradox because the result appears impossible but is demonstrably true. The Monty Hall problem, in its usual interpretation, is mathematically equivalent to the earlier Three Prisoners problem , and both bear some similarity to the much older Bertrand's box paradox .

Television pickup is a phenomenon affecting the British National Grid electricity transmission network. As the British public tend to watch the same TV programmes and take advantage of breaks in these programmes to operate electrical appliances (particularly kettles) they cause large, synchronised surges in electricity consumption. National Grid staff devote considerable resources to predicting and providing electricity supply for these events which typically impose an extra demand of around 200–400 megawatts (MW) on the Grid. Short term supply tends to be found from pumped storage reservoirs , which can be quickly brought online, backed up by the slower fossil fuel and nuclear power stations.
