Question

Alma has a bag with 26 tiles, each with a different letter of the alphabet. She randomly chooses a tile and places it on a table. She then randomly draws another tile and places it to the right of the first tile, and then repeats this one more time. What is the probability that this results in the word "dot"?

Answer 1

There are 26 tiles in the bag.

To spell the word DOT, we have to select 3 tiles from the bag.

This can be done in

26C3 ways.

Out of this, the word DOT can be correctly spelled in only 1 way.

Hence, the Prob.

=1 / 26C3
