Question / thought experiment from somewhere (todo: track this down): > If you needed to get a pizza in the next 30 minutes or else you die, how would you order? > Correct answer: order a pizza from as many places as possible, to maximise the chance that *at least one* arrives within 30 minutes. So there's a couple of things going into this: - Independence -> many pizzas from one place obviously doesn't help, because they're all correlated with each other (i.e. will arrive together - probably in fact later because they'll take longer to prepare...)
