A computer generates a 4-character computer password of 2 digits followed by 2 letters so what is the number of passwords?

4 charecters

67,600 - in the first spot there could be any digit from 0 to 9 or 10 digits same is true for the second spot In the third and fourth spots there could be any one of the 26 letters in the alphabet so it looks like this 10*10*26*26 =67,600
