Formulate the binomial coefficient expression.
Divide out the common 43! term.
Compute the final integer count.
There are precisely 13,983,816 unique 6-number ticket combinations from 49 numbers, yielding a 1 in 13.98 million jackpot probability.
| Input Scale | Standard Output Range | Variance Band | Recommendation |
|---|---|---|---|
| Low Baseline | 0.00 – 25.00 | ±1.5% | Optimal for conservative estimations |
| Median / Standard | 25.00 – 100.00 | ±0.8% | Benchmark standard for commercial workflows |
| Elevated / High | 100.00 – 500.00 | ±0.4% | Recommended for high-throughput modeling |
| Extreme Maximum | > 500.00 | ±0.1% | Verify input constraints for boundary saturation |

In combinations, the order of selected items does NOT matter (e.g. {A, B} is identical to {B, A}). In permutations, order DOES matter (e.g. locker combinations, pin codes, or race finishes where 1st and 2nd place are distinct).
