Answer:
Explanation:
There are 26 letters in the alphabet and 10 digits that you can use (0,1,2,3,4,5,6,7,8,9)
As a result, we can find the number of combinations by doing the following:
26 x 26 x 10 x 10 x 10
since the first two symbols are alphabets and the last three are digits. After doing the math you get
26 x 26 x 10 x 10 x 10 = 676000 => You can make a total of 676,000 PIN codes
