中奖的概率几乎为0,2500万,3000万都没人中,这几期lotto的销售额每期都有好几千万,你可以假定有一个人买了几千万也中不了大奖

Go back do some homework before you speak, Jagar.
Chances winning the grand prize (got all 6 numbers) is very easy to calculate.
(6 * 5 * 4 * 3 * 2 * 1) / (49 * 48 * 47 * 46 * 45 * 44) = 1/13,983,816
For 6/49, now each play is $2, (used to be $1), If you gave me $2 * 13983816, I can buy up all the combinations, $2 on each combination.
I am guaranteed to win one grand prize.
Or, if you are not yet university educated, I am sorry. Forget about it.
