Blimey you're swapping the odds a bit quick, your original post said 4/1 on, if you don't understand what that is you shouldn't be putting bets on things. Now you're saying the bookies are giving 4/1. So to be crystal on this, your first post means take £4, look at your hand, hide your thumb, and that's four, that's what you would have to put on to win, hide three of those fingers, to win £1, have you got that.
Now you've got 4/1, remember that one little finger you were holding up, but don't tell anyone, you'd only need to use that one to win £4, have you got that, and quite frankly, I'd give Rossi a 20% chance of losing the title, if he's in the first three at mid season, wow, that's a toughy for you, get yourself a piece of paper and a pencil, remove socks, that may help, and work that one out, answers before close of school, what a joke you lot are, you don't know when your f*cked.
What about a brain teaser then, work out 4 into 100, then add it to your 80% you muppet, you can't add up either.
