How the maths works
Lottery odds come from combinatorics — counting how many ways you can choose a subset of numbers from a pool. The formula is:
C(n, r) = n! / (r! × (n − r)!)
where n = pool size, r = numbers to choose
For El Gordo de la Primitiva, you pick 5 numbers from 1–54 (a pool of 54 numbers):
Then you also pick 1 Key Number number from 0–9 (a separate pool of 10 numbers):
Since the two draws are independent, multiply them together:
Each ticket covers exactly one combination, so your jackpot odds are 1 in 28,462,590 — which matches the official published odds of 1 in 31,625,100.
Does buying more tickets help?
Yes — but the improvement is smaller than you might think. Each ticket adds one independent combination to your entry. With n tickets, your jackpot odds become n in 31,625,100:
