A standard entry picks 5 numbers from 47 plus 1 from a separate pool of 27. The number of possible combinations is:
C(47, 5) = 1,533,939 × C(27, 1) = 41,416,353

Odds of winning any prize
1 in 23.49
Sum of all division probabilities — usually the number the ads quote.
Odds of the top prize
1 in 41,416,353
One standard game. Two games doubles it — and it's still tiny.
How long are these odds? Winning the top prize is about as likely as calling 25.3 coin flips in a row correctly (225.3 ≈ 41,416,353). If you bought one line every draw, at two draws a week you would expect one top-prize win roughly every 398,234 years.
