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 Ontario 49, you pick 6 numbers from 149 (a pool of 49 numbers):

C(49, 6) = 49! / (6! × 43!) = 13,983,816 combinations

Each ticket covers exactly one combination, so your jackpot odds are 1 in 13,983,816 — which matches the official published odds of 1 in 13,983,816.

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 13,983,816:

TicketsJackpot oddsApproximate cost
11 in 13,983,816~$2 USD
51 in 2,796,763~$10 USD
101 in 1,398,382~$20 USD
501 in 279,676~$100 USD
1001 in 139,838~$200 USD
Buying 100 tickets still leaves your jackpot odds at roughly 1 in 139,838 — statistically indistinguishable from 1 ticket. Syndicates can pool entries but do not change the underlying probability per ticket.
