What is the probability of getting a license plate that has a repeated letter or digit if you live in a state that has one numeral followed by two letters followed by six numerals?

This may not be quite as straightforward as it first seems. In the UK, which has a different letter-number combination, some letters are not used so as to avoid confusion for example O and 0, or I and 1. If that is the case, then the probability of a particular digit is not 1/10.

Also, some letter combinations that spell offensive words are disallowed. The consequence is that not all 26 letters of the alphabet are used and those that are may not be used in the same proportion. This will probably not apply if there are only two letters.

How can you use measures of central tendency to distribute an amount evenly among a group of people?

It may be approximately possible.

Calculate the mean and give everybody an amount equal to the mean.

Unfortunately, that may not be possible. If you have 10 pounds (sterling) and 3 people, the mean is 3.33 recurring. Unfortunately, the coinage does not allow recurring decimals. So you can share out 9.99 @ 3.33 each but are left with 0.01 that is not shared.
