Answer:3,276,000 possible license plates for this state

Step-by-step explanation:The order is important. For example, if the letters are EM, it is already a different plate than if the letters were ME. So we use the permutations formula to solve this question.

Permutations formula:The number of possible permutations of x elements from a set of n elements is given by the following formula:

LettersThere are 26 letters in the alphabet. In the plate, there are two letters. So permutations of two from a set of 26.

DigitsThere are 10 digits. In the plate, there are four. So permutations of 4 from a set of 10

TotalMultiplying these values

650*5040 = 3,276,000
