Imagine the scenario, you are in London and jump aboard an iconic, Routemaster bus. Climbing upstairs you witness a fight going on. Being a right-minded type, not to mention a black belt in Judo who can take care of yourself, you wade in and calm everything down. Talking to the 2 combatants (who happened, by pure coincidence, to be called Barak and Mitt) you discover it all started over a mathematical debate. This was the issue: Barak insisted that there was a better than 50:50 chance that 2 people on the bus celebrated their birthday on the same date and Mitt just wasn’t having any of it and he was letting Barak know this! As it happens, Barak was correct! How many people must there have been on the bus (before you got on) (by the way, Barak was ignoring people born on 29 February) Answer next time
