Here is how probability works in an example.

Say you have 10 boxes.

In each box they have 11 pieces of paper inside.

On 1 piece of paper has a number. The rest are blank.

You * the hand in the first box and pull out 1 piece of paper

You have (if I did the math right) 9% in getting the piece of paper with a number on it.

Here is the fun part,

Each box you try and pull the paper with a number on it all have the same chance. So by your logic you should have a 90% chance with 10 boxes to get a piece of paper with a number on it. Sadly that isn't how that works as probability isn't ac*ulative since every box has the same % as each other.
