Pearls!

The odds that an unopened Oyster contains a Pearl are approximately 1 in 12,000 (0.008%)

That's why pearl diving is like being in a garage band, sure it's a fun hobby but you're never gonna make enough money to feed yourself. But you can eat the oysters. Good advice dad.

Italia!

UPDATE: The current odds that Italy will repeat as World Cup Champions are approximately 1 in 14 (7.14%)

I couldn't find a proper picture of an Italian player diving- the cornerstone of their strategy being to roll around on the ground, grab a knee in pretend agony and groan every time an opposing player comes near them. Instead, enjoy this legit photo of Zidane punking an italian for real, probably to see what happens when one actually gets hurt. Zidane's a dick too though. Go Argentina!

Astronauts!

The odds of becoming an Astronaut are approximately
1 in 13,200,000 (0.0000075 %)

Keep in mind that not ALL astronauts are chosen through a lottery so if you really want it you probably have to work out and train on one of those spinning things. But the odds of becoming a space chimp are closer to 1 in 8.
