The odds of winning the lottery may be 21/2 million to 1 if you bought a ticket... I'll give you that the odds are incredibly slim... but let me guess what the odds of winning would be if you didn't even buy a ticket.... hmmmm... I suppose you might find the lucky ticket flying about down the street... but now we're talking about the same odds as having a successful satellite land on Mars.... Doh! Wait just a minute!
What I'm saying is that if you put your money on backing a horse at 100 to1 you might not win as much, but you stand an infinitely better chance of winning.
