Been off the grid for a while...
A couple of weeks ago, Josh Hamilton of the Rangers hit a grand slam that got an above-average amount of attention, since it was tied into a promotion being run by a flooring company. The title of this article describing the homer could instead be "Josh Hamilton's grand slam yields big insurance payout":
Somebody, somewhere, in some insurance company, sold coverage for this promotion. And that same somebody (we hope) must have sat down and calculated the probability of Hamilton hitting a grand slam over a one month period, and set the premium based on that probability.
Summary: insurance is gambling.
