What starts as an informal chat with no planned focus becomes, at one point, a discussion (by two comedians with no maths background) of the difference in chances for a group seen as a whole, and the chances for any individual member of that group. Along the way we talk about comedian Sofie Hagen's recent mini-twitterstorm about an ad by Cancer Research UK, and an incredibly abstract example involving a lottery where black people are given more tickets than white people. This lottery does not exist, as far as we're aware.

WARNING: CONTAINS OFF-THE-CUFF MATHS.

This is in no way influenced by the fact that neither of us is ever on Mock The Week.

Definition of a bell-curve here: https://en.wikipedia.org/wiki/Normal_distribution - not to be confused with the book 'The Bell Curve', which we haven't touched yet, but may at some point.
