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 UK Thunderball, you pick 5 numbers from 1–39 (a pool of 39 numbers):
Then you also pick 1 Thunderball number from 1–14 (a separate pool of 14 numbers):
Since the two draws are independent, multiply them together:
Each ticket covers exactly one combination, so your jackpot odds are 1 in 8,060,598 — which matches the official published odds of 1 in 8,060,598.
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 8,060,598:
