That's Not So Random!

Greg James and Bella Mackie didn’t pay much attention at school. So they’re asking Britain’s most inspiring teachers to show them what they missed in this series of fascinating and fun lessons.

This week it's maths with Mr Fisher (call him Rob) who teaches Greg and Bella why it really annoys him when people say "that's SO random", when the things in question aren't random.

Along the way we learn what random actually means, with examples from the National Lottery and playlist shuffle, and why humans are so bad at choosing things randomly.

Bad students of all ages are welcome. Expect brilliant teachers, captivating subjects but absolutely no homework.
