First sample space: 26

Second sample space: 26 x 26 = 676

Third sample space: 26 x 26 x 26 = 17,576

--------------

In the sample space of 26, C will only appear once.

--------------

In the sample space of 676, C-A will only appear once.

---------------

In the sample space of 17,576 C-A-T will only appear once.

---------------

Chance of this scenario taking place:

1/17,576

That's a 1 in 17,576 chance.
