Yes. Another Terry Gilliam film. He was a brilliant director. Had the pleasure of rewatching Fear and Loathing in Las Vegas the other day.
It's an interesting question. Mathematically it is straight forward. The 50% chance at $100 million button is the better choice, as on average the it pays off $50 million per push. So from a purely mathematical perspective, it outperforms the sure thing by a factor of 50 to 1. Real life is a bit more complicated though. $1 million is still life changing money, and it is a sure thing. You know what you are getting, you can rely on it. I can more easily accept taking $1 million, knowing that I gave up the chance for $100 million than I could rolling the dice and ending up with zero and squandering guaranteed life altering money. So while the maths is clear, and I know which one I "should" choose, I'd probably play it safe and take the sure thing. I'd be willing to give up the best case scenario ($100 million) in order to eliminate the worst case scenario (ending up with nothing). I am more risk averse by nature.
