I think you will like this particular RadioLab podcast on Stochasticity:
This hour, Radiolab examines Stochasticity, which is just a wonderfully slippery and smarty-pants word for randomness. How big a role does randomness play in our lives? Do we live in a world of magic and meaning or … is it all just chance and happenstance? To tackle this question, we look at the role chance and randomness play in sports, lottery tickets, and even the cells in our own body.
And catch the Stochasticity Bonus Video.
