Does buying more than one lottery ticket per drawing increase your
odds of winning proportionately? Example which correct: if one ticket=
1/50,000,000 odds then does two ticket= 2/50,000,000 or 1/25,000,000
odds? Please explain answer.

Cliffy, that is exactly correct if you make sure that every ticket you
buy plays different numbers.  If the numbers you play are random or
not specifically chosen so that you have different numbers on every
ticket then your odds will increase slightly less with each additional
ticket you buy (because the odds of playing the same numbers on 2
tickets increases with the more tickets you have).

The odds against winning lottos like Big Game or Powerball run around
100 million to one (Big Game 80 million to one, Powerball 120 million
to one). Someone calculated that if you bought 50 tickets every week,
you'd win the jackpot about once every 30,000 years. To do so within a
reasonable human time span of 30 years would require 50,000 tickets a
week. At a buck a ticket, that's $2.6 million a year for 30 years.

If a governor proposed a tax on morons who can't do math--
specifically on minorities who can ill-afford to waste money-- (s)he'd
be voted out the next election. That's why they promote lotteries.

Cynics see lotteries as a voluntary tax on stupidity. I view it as a
tax on despair. But I'm not here to preach.

I just want to say that the purchase of additional tickets beyond the
first one serves no real purpose. The first ticket changes your
chances from zero to astronomical. Additional tickets make the odds
less astronomical, but still astronomical.

Better you should save the cash and spend it on going to school.
There's a guaranteed payoff in that.
