A license plate consists of 1 number followed by 2 letters followed by space. After the space the 3 entries can be either a number or a letter. How many license plates are possible using this method given repeats are allowed?

Answer 1

1st character: 10 numbers (0-9)

2nd character: 26 letters

3rd character 26 letters

5th character: 10 numbers + 26 letters = 36

6th character: 10 numbers + 26 letters = 36

7th character: 10 numbers + 26 letters = 36

total number of combinations = 10 * 26 * 26 * 36 * 36 * 36
