Q: Why doesn’t a wealthy person buy every number for $175 million and ensure themselves a $500 million return ?
A: Because if two others get the same idea, then would have three people paying $170 million but they would only win 500/3 = 166.67 million each.
Guaranteed to lose money.
Just an example of how multiple winners changes the odds, and judging by the crazy people in my office and sdr’s mom, there’s gonna be a few more hands in the pot.
