Winning $301M Powerball jackpot numbers drawn: 21-39-40-55-59 and 17

A $301 million jackpot is on the line in tonight's Powerball drawing. Did you win?

Here are the winning numbers: 21-39-40-55-59 and Powerball is 17

There are only two drawings left before a change in Powerball rules makes it much harder to win big.

The cash value of tonight's drawing is $191 million.

After Sunday, the chances of winning the jackpot go down, but the size of smaller cash prizes goes up.

Of course, winning the Powerball is virtually impossible. The odds of getting all the numbers is 1 in 175,223,510. CNN reports you have a better chance of becoming an astronaut, dating a supermodel - maybe even being attacked by a shark or struck by lightning - simultaneously.
