Answer: 325
Step-by-step explanation:
Combination is a way to calculate the total outcomes of an event where order of the outcomes does not matter where as a Permutation is a way of arranging the elements of a set into a order or a sequence . Here order matters.
If we want to create password with 6 different letters then order matters.
Hence, we use permutations.
The number of passwords created is given by :-
[tex]^{26}P_6=\dfrac{26!}{2!(26-2)!}\\\\=\dfrac{26\times25\times24!}{2\times24!}=325[/tex]
Hence, the number of passwords created = 325
