Got out my calculator today.

If you spent $4000 a week on Powerball tickets you should expect to win ONCE in 1405 years. Once in 108 years to win the $1 million.

Another way to look at it, if you buy $900 worth of Powerball tickets you have the same odds of winning the grand prize as you have of drawing a royal flush with one draw of 5 cards off a well shuffled deck.
