Lotto

[dr. d]

Not per draw. In 6/55 if the Jackpot reaches more than P580M, you will win 100%, albeit a small amount, if you spend P579,793,500.00 [(28,989,675, the odds of winning at 6/55 lotto) x P20].

AND the chances of winning "is", and not "become", astronomically small.

i agree. you win.
but,
what if someone chose a lucky pick and also got the winning combination? eh, 'di lugi na tayo nang 290 million...
or, what if someones made the requisite calculations as you did, and bought the requisite tickets, exactly what you did? lugi na rin tayo ng at least 290 million...
it was already discussed some time ago, by a numbers person (math prof?). his warning was something like, "yes, you can compute the threshhold amount, but so can others. and i am not the only math major in the city in need of money."
"if you can think about it, so can others."
tama si papi.

some time ago,
there were 433 winners in one lotto event.
the lotto folks were being questioned about this, because having 433 winners is literally too good to be true. but upon investigation,
it turned out, all the winning bettors were betting on a particular combination that had a basis. the numbers were not random, but were based on certain features that all the winners were using. in this instance, i recall, the winning numbers were multiples of 9 .
bottomline, if there is a basis for one's choice of numbers, do not assume that you are the only bettor using that basis.
