Talk:How the 'A' Stole Christmas/@comment-25547603-20141111193658

So I had this question on an exercise of maths/logic and I answered wrong :( Let's see if you're better than me! I'll tell you in a PLL Version LOLOLOL

So, Spencer gets a code to find out who A is. This code has three numbers: 0, 6, 9 and three letters: X, H, I. You have to use each number/letter only once, so the code has 6 characters.

Spencer writes the code. Hanna loses it, but she find a piece of it.

/ 9XHI /

and she doesn't know what the code is. How many possible combinations of the code we could have?

a. 4

b. 6

c. 8

d. 12

e. 16
