Lottery fever is sweeping the country. The Mega Millions jackpot sits at $1.02 billion, becoming the fourth largest jackpot in U.S. lottery history. The lucky winner would have the choice to either receive $1.02 billion with the annuity option or an estimated $602.5 million with the cash option. Lottery expert Richard Wheeler says if you want the jackpot, don't pick birthday numbers. Wheeler also says buying tickets with a bunch of co-workers or friends could increase your chances.
