Answer :

Answer:

2,620,800  license plates can there be in this state if the first digit cannot be 2, and repetition of letters and numbers is not permitted.

Step-by-step explanation:

Here the licence plate has 4 numbers and 2 uppercase letters.

Given: The first two numbers CANNOT be 2.

           Repetition in NOT permitted.

Now, according to the question:

The available options in the first number = Any number other then 2

= 9 options.

The available options in the Second  number = Any number other then 2  and the first number as  Repetition in NOT permitted.

= 8 options.

The available options in the Third  number = Any number other then first     and second  number as  Repetition in NOT permitted.

= 8 options

The available options in the Fourth number = Any number other then first     second and third number as  Repetition in NOT permitted.

= 7 options

The available options in the Fifth place Alphabet = 26 options

The available options in the Fifth place Alphabet = Any number other then first alphabet  Repetition in NOT permitted.

= 25 options

So, the total number of options =   PRODUCT OF ALL POSSIBLE OPTIONS

= 9 x 8  x 8 x 7 x 26 x 25

= 2,620,800 options.

Hence, 2,620,800  license plates can there be in this state if the first digit cannot be 2, and repetition of letters and numbers is not permitted.
