A lotto odds

Two lottery jackpots are up for grabs this week. The prizes add up to more than half a billion dollars.

But don’t count on getting doubly lucky.

The only thing more astronomical than the amount won by a double winner would be the odds against winning both at the same time, which would be about one in 31 quadrillion (based on the 175.7 million chance of winning the Mega Millions jackpot multiplied by the one in 175.2 million chance of winning the Powerball jackpot).

Still, someone — at least two someones, that is — could get lucky big-time this week.

A $360 million prize awaits the winner of the Powerball drawing at 10:59 p.m set tonight.
Friday in the Mega Millions drawing, the prize will be $190 million.
