Three Things You Need to Know About the Lottery
Written by
A lottery is a game of chance in which participants purchase tickets for a drawing to determine the winners of prizes, such as money. Lotteries are typically run by governments or private organizations and are regulated to ensure fair play. The first known lotteries date to the Low Countries in the 15th century, with town records from Ghent, Utrecht, and Bruges showing that local officials used them for various purposes, including helping the poor and building walls and town fortifications.
Today, state lotteries are thriving and Americans spend an estimated $100 billion each year on tickets. But they have a long, sometimes rocky history in America. Here are three things to know about them.
1) It’s a game of chance
Although the concept of winning a prize through a lottery might seem simple, the odds are complicated. “You’re putting your money at risk, and you hope for the best,” says Tim Chartier, a mathematics professor at Davidson College and visiting distinguished professor at the National Museum of Mathematics in New York City. “It’s a bet on the outcome of an event, which means there is an element of luck involved.”
A good way to understand this is to look at how much you stand to win in a given drawing. The number field and the pick size both have an effect on your chances. The smaller the number field, the better your odds of winning. “For example, 42 is better than 49,” he explains. “32 is better than 35.” And so on.
The bigger the number field, the more difficult it is to win. This is because there are more possible combinations, making it less likely you’ll hit any one of them. The other factor that affects your odds is the amount of time you have to wait for the jackpot, which is based on an annuity calculation that accounts for interest, Chartier says. When interest rates rise, so do the jackpots, even if the actual cash amounts are unchanged.
It’s hard to predict when the next big jackpot will appear, but there are some tricks that can help you prepare for it. For instance, you can find out which numbers are most often drawn by looking at past drawings. You can also choose your numbers carefully to increase your chances of winning. Chartier suggests avoiding numbers that are confined to one group or those that end in the same digit. “Variety is the spice of winning,” he says.
Remember that the most important thing to keep in mind when playing a lottery is to treat it as entertainment, not a financial bet, says Chartier. And don’t use the money you’re putting into a lottery ticket to fund other expenses or investments, he adds. “If you do that, you’re gambling with money you should be using for something else.” Read more from NerdWallet’s Money team.
