can we mathematically calculate a system similar to lottery with one difference - that everyone gains profit in a given time......... or, if not everyone, at least the majority of people make profits at a given time ............ personally, I'm not some good mathematician, so when I try to calculate this I always end up in a circle ......example....in one day 20 euros pay 5000 people = 100 000 euros (important note: the goal is that all who have paid (or at least the majority of the people) get a profit) ... 100 000 euros : 10 winners = 10 000 euros .... so, 10 000 euros got 10 people (0.2% of players got a win - in one day) ....... however, if the rule is - the winnings goes in order 1, 2, 3 etc., so the first 10 players got a win (10 000 euros), and the next 10 000 euros should be paid to the next 10 players .... now, the problem I come across is this - the monthly fund is 3 000 000 euros : 300 winners = 10 000 euros ........... however, If you try give all the 5000 participants money that would be in a 16 months ............ and if in those 16 months (480 days) each day each participant pay 20 euros, he would have paid 9600 euros, rounded 10 000 euros ... in other words it would have a positive zero - circle ........ What I'm interested in is can you mathematically calculate a system where at least a higher percentage of people would get and how it would look in numbers?

**........imagine you are a manager of a lottery and your goal is to enable high percentage of winning, how would you mathematically do it?**
