Series 1, Episode 7
helps out Dara O'Briain
on the penultimate episode of the brain-teasing series. However, it's a case of the blind leading the blind tonight, as the first fiendish challenge is one that requires being blindfolded.
There are 100 coins on a table. 90 are heads up, and ten are showing tails. Crafty Maths professor, Marcus du Sutoy wants us to make two piles of coins, both with the same number of tails up coins in them. Sounds easy, but it's not when you can't see a thing. Will the application of some basic mathematics help you come in from the dark and see the light? You bet it will.
