Tickets for the lottery are available online at various sites, but it is often difficult to verify the validity of the tickets.
In April, a lottery operator in New York claimed that more than 20 million of the $10 million tickets were counterfeit.
According to the Associated Press, the New York Police Department has found that online auctions have generated more than $1.2 billion for counterfeiters, which includes nearly $400 million to $600 million for each of the last two years.
It is not known how many of the winning tickets are legitimate.
As the AP noted, tickets can be purchased online and purchased in person at casinos and other venues, and sometimes in person.
The odds on winning tickets can vary widely.
For instance, one study showed that about 90 percent of winning tickets were either fraudulent or fake.
In the lottery, the prize is usually worth more than the cost of admission.
The prizes are not necessarily based on the number of tickets sold.
For example, tickets for the Biggest Loser competition, which ran from 2007 to 2012, had an average value of about $25.
The average prize for the Super Bowl was $1 million.
