• Total balls in pool: The number of unique numbers available to draw from.
• Number of balls drawn: How many numbers are selected in a single draw.
• Order matters: If the order of selected numbers affects the result.
• With replacement: Whether a number can be selected more than once.
  "With replacement" means the same number can appear multiple times (rare in real lotteries).
  "Without replacement" means once a number is drawn, it can't be drawn again (common in real lotteries).
