I don’t even know how to calculate the odds on MegaMillions anymore. I must not be alone in not liking it because the jackpots seem like they are growing way more slowly now.
I was never more than a casual consumer of these lottos when the jackpot got big enough, but with the $5 price tag, I think mega millions has to reach in the ~$2.5bn range to be a marginally defensible gamble.
