How do you read the odds numbers? Is 8/1 likely or not likely?

I didn't get this either. Some numbers are 1/25, which seems like 1 in 25 chance = 1/25 = 4% Yet other numbers are 6/1, which is 600%.

In UK gambling conventions, 8/1 means you win £8 on a £1 bet. So 12.5% chance, if the bookie is a non profit.

Close :). You receive £9 on a £1 bet (you get your outlay back), so it's 1/9 ~ 11.1%
