Some basic calculations explaining what chance is to chose 6 numbers within 49 ones.
In a typical 6/49 draw, six numbers are drawn from a range of 49 and if the six numbers on a ticket match the numbers drawn, the ticket holder is a jackpot winner—this is true no matter in which order the numbers appear. The probability of this happening is 1 in 13,983,816. Full calculation is at the website Wikipedia http://en.wikipedia.org/wiki/Lottery_mathematics You can find there table of probabilities for other numbers chosen from 0 to 6. For example, if you want to win "3" probability is one in about 57, that means you must buy 57 single tickets to draw 3 lucky numbers. For lucky "4" probability is much lower, only one in 1032. For lucky "5" probability is 1 in 54200. So as you can easily notice the probability decreases at geometric rate.
