For the five characters of the five-character password, the first three slots are already taken for the initial F, J, S, the password would become,
FJS_ _
The last two slots could be any of the even digits. In the fourth slot, Fiona can have any of the 5 values. On the fifth slot, she can have only 4 choices as the other digit was already used. Multiplying 5 and 4, the answer would be 20.
It is a straight, horizontal line!!!
Yes
16/4 is 4
8/2 is 4 as well
Making them equivalent
7 x 6 is 42 hope that helps
