If I had 10 dollars to spend on a 1 dollar lottery draw, would I have more chance of winning if I spent all 10 dollars in one draw or bought 1 dollar tickets for 10 separate draws?
Edit: in terms of lottery definition, you pick 6 numbers from a pool of 49 numbers (1-49), that is classed as one lottery ticket. So each 1 dollar represents a selection of 6 numbers. Across multiple tickets you can pick the same numbers as appear on your previous tickets. If you are familiar with EuroMillions or UK Lotto, it's that kind of lottery.

Edit 2:
Let me re-phrase the question. The probability of winning the jackpot in the lottery is 1 in 13,983,816.
Would buying 10 tickets for one draw change those odds to 10 in 13,983,816 ? and if so is that better than playing in 10 different draws at 1 in 13,983,816 odds each?
