Participation in the lottery is extremely easy because they will charge you a very little amount for participation. And the prizes for the lottery are usually mouth watering and very big.
That is the main reason why we see a lot of participation in the lotteries although most of the participants know that winning is extremely unlikely in the lottery.
With lottery, they house always have the greater advantage than the participants and so it's not new that most of the times it's very unlikely the participants wins because the odds they win are always and usually high due to the fact that there are many participants and only a few can win at a time, if everyone wins definitely the house will not be able to pay all at once.
The charging of little amount to be able to participate in the lottery draws is because they want to really have many participants enough to be able to raise the funds needed to find the winners while they will be having more than enough left behind to be able to keep as their own profit while the keep business afloat regardless of the the number of participants, knowing that the entry amount is really small which could mean that they are going to get a good number of people playing, they will tighten the chances of winning so that not everyone can win at once els payment will really be chaotic.
