Hello!
We have a 1/5 chance of selecting a certain letter, and we do this two times. Therefore, we divide below.
1/5/2=1/10
Therefore, there are D) 10 ways.
I hope this helps!
There are 5 letters.
You can pick from 5 letters for the first letter.
You can pick from 4 for the second letter.
5 * 4 = 20
This gives you a total of 20 different 2-letter words.
If you were creating different 2-letter words, then the order would matter, and the answer would be 20.
In your case, you are just asked to pick two different letters, so if you pick a "c" followed by an "o", it's the same as if you had picked an "o" followed by a "c", since you still have the same two letters, "c" and "o", so you must divide 20 by 2 to get 10.
Answer: d. 10 ways
