We continued the topic of probability with further coin tossing experiments, and Jared duly noted that the longer one tossed the coin, the closer we got to the expected 50-50 outcome, despite randomness in the order of heads and tails. In order to demonstrate the power of mathematical rules in probability, I introduced Jared to the 'Monty Hall Problem' – we tested it using three cups and a coin. After multiple runs, during which several of the school staff participated, the 2/3 vs 1/3 rule remained pretty solid (to Jared's delight!).
