Lottery Luck In 1996, a New York couple won \$2.5 million in the state lottery. Eleven years later, the couple won \$5 million in the state lottery using the same set of numbers. The odds of winning the New York lottery twice are roughly 1 in 16 trillion, described by a lottery spokesperson as “galactically astronomical.” Although it is highly unlikely that an individual will win the lottery twice, it is not “galactically astronomical” that someone will win a lottery twice. Explain why this is the case.
