Where:
Explanation: The formula calculates the chance of any single ticket winning the jackpot.

Tips: Enter the total number of possible combinations in the lottery. This is typically provided by the lottery organization or can be calculated based on the game rules.
Q1: How do I find the total combinations?
A: For a simple lottery where you pick n numbers from N possible numbers, the combinations are calculated as N choose n (combinations formula).
Q2: Does buying more tickets increase probability?
A: Yes, buying t tickets changes the probability to t/T where T is total combinations.
Q3: Are all combinations equally likely?
A: In a fair lottery, yes. Each combination has exactly the same chance of being drawn.
Q4: What about lotteries with bonus numbers?
A: These require more complex calculations that account for matching different numbers of main and bonus balls.
Q5: Can I improve my odds?
A: Mathematically, no. The only way to improve odds is to buy more tickets, but the change is negligible for large lotteries.
