These are your odds of winning the Powerball or Mega Millions

The odds that you’ll win the $418 million jackpot in Friday’s Mega Millions drawing are really, really bad.

And the odds that you’ll win $550 million in the Powerball drawing Saturday are similarly stacked against you.

The likelihood of winning both? Forget about it.

Chances Of Hitting The Jackpot

The Mega Millions odds are 1 in 302.6 million. That’s more than 2,000 times less likely than being killed by a lightening strike or an earthquake.

The odds of winning Powerball are only slightly better—1 in 292.2 million.

If it seems like the odds are even worse than they used to be, they are.

Both games have increased the choice of numbers people can play, which makes it less likely that someone will get all six numbers right. Powerball lengthened its odds in late 2015, while Mega Millions made the change this past October.

Having jackpot winners less frequently means that the top prizes roll over more and get bigger. And that attracts even more players. Right now that cycle is working perfectly.

In fact, this is the first time ever that both games have offered jackpots of $400 million or more at the same time.

And that’s prompting people to buy tickets to both games, rather than just one or the other.

What Are The Chances Of Winning Both?

So that raises the question, what are the chance of winning both games this week and walking away with jackpots totaling nearly $1 billion?

That would be 1 in 88 quadrillion, or 1 in 88,412,922,115,183,000 to be precise. If quadrillion isn’t a term you deal with very often, think of it this way—it’s 88,000 trillion, or 88 million billion.

Or if you’re one of those people who do better with percentages: You have a 0.0000000000000011 percent chance of winning both games.
