For simple mental exercise for everyone & to calculate the odds in toto - a chance to win millions with mere 6 numerals within a range of 49, a bettor/gambler will have to buy ALL 49 numerals on a single bet to obtain 100% sure win. But no organizer of Toto draws will allow such, or such orgs will not exists. Thus only a few range of numerals are allowed, to ALWAYS ensure the 'House' ( Singapore Pools) wins.
If you buy a single ticket, using the computer to select your numerals or on your own choice of 6 numbers, your odds of winning is only est 12%, (6 numerals divided by 49 numerals X 100%) while the House ( Singapore Pools) hold the odds of 88% to win against your choice. ( And that's not even calculating the odds yet of the numbers of bettors for that particular draw date & the amount to be shared by the winners)
To better the odds, the more numerals you are able to buy, the higher your chances of so called 'winning', from system 7 to system 12 numerals - with odds at 24% to win against the House who holds 76% of a chance to win against your ticket. The odds are still against you, for the near thousand you had spent on a single ticket.
Singapore Pools, unlike other nations or private betting system which only enriches the operators, SP is controlled by the elected govt & winnings are carefully audited so that every single cent goes to funding charities & social expenditures of nation. Your single ticket/bet slip for that one day may be just $1, but should 3 million consumers buy, SP will have collected $3 million. Most will buy more than 1 betting slip, & with higher odds to win, eg at $7/ system slip, it would be $21 million into Singapore Pools...
Should one hopes to beat the odds, some took to HISTORICAL evidences of certain numerals that often keeps appearing as winning numbers, like in 4D- an easier system for betting & odds, as it has only 4 numerals instead of 6.
While it may not be a quick solution to win tomorrow's $8million dollar windfall (which is tax free but only taxed if you place in banks, earning interest as dividend earnings which are only then taxable), but so long as one keeps to such numerals, it will hit the top prize one day like 4D based upon current Humanity's knowledge of mathematical probabilities, which there is still SO MUCH unknown & to know, not just to enrich oneself, but to elevate Humanity to prevent crisis & calamities proactively than reactively.
While without money, everything is nothing, but still money is not everything. There is more to life than money alone. Many claimed that they will do good once they have money, but sadly, money gives power & power only corrupts, proven time & time again in Human history.
So bet/gamble responsibly to family & loved ones whom are priceless in one's lifetime. Never bet/gamble more than what one can afford to lose, not just in terms of money but life itself to oneself & loved ones. There are no get rich fast schemes in the World, except to be a heartless scammer whom eventually will meet retribution one way or another. Work hard, work smart, earn an honest living, then the path to greater securities & acheivements in life - home, financial, love, etc, awaits...
All the best. :-)
