Question 1201686
<font color=black size=3>
26 letters in the English alphabet
26^3 = 17,576 different 3 letter combos where the letters can repeat.


Consider the case all 4 numeric digits are even.
There are 5 even single digits (0,2,4,6,8)
There are 5^4 = 625 ways to form a four digit number that has all even digits.
This is out of 10^4 = 10,000 ways to form a four digit sequence. Zero can be at the front.
10,000 - 625 = 9375 ways to have a sequence of 4 digits where at least one of them is odd.



Recap:
17,576 ways to form the letters portion
9375 ways to form the numbers portion


So,
17576*9375 = 164,775,000
represents the number of possible license plates.
