Asked by Charlene

I just did this Quiz and I dont understand how I got this wrong. The question is

How many 2-digit numbers can be formed using the only digits 2,3,5, and 6, if the digits are not repeated within a number.

A.11
B.12
C.10
D.2

I picked 10 but the score sheet says its 12. How is that possible?
