Oh, well if my chances of winning are 2% better than I thought, I'll have a ticket now... The value of the prize doesn't come into it. It's the chance of winning that is important if you are considering a gamble. If that wasn't the case, everyone would be backing the 100/1 outsiders at the races (which they don't, or at least only the idiots do). Oh and btw, it is a 50/1 shot.
