There's 40 cars in a race, with only three winners,I pick only three cars and all three win what are the odds of this happening.
In my opinion, that might just be good luck or you knew that that the three cars would win. Or you picked the cars just after they won. That's odd but it can happen. We can also say it was a coincidence.
3 out of 40 chance that you would guess that right Congratulations!
With luck like that I would play the horses
