A)
The two digits can be arranged in 10x10 or 100 ways
B) Assuming that KRIS must remain that way, there would be 100 such plates,
e.g KRIS56 is one of them
Kris wants to order a personalized license plate for her car. The plate is to have the 4 letters KRIS followed by any two digits.
Part A: How many different ways can the two digits be arranged?
Part B: Suppose the plate has KRIS followed by two additional digits. How many different plates of this type are there?

how is it 100 ways?
I'm not sure, but shouldn't the answer for Part A be 2!
= 2 * 1
= 2 different possible ways
I mean, just think about the question. If the digits follow the letters KRIS, how can you arrange them in a hundred different ways? Let's say the numbers are 5 and 6. You can arrange them either 5,6 or 6,5. You can't arrange them 100 different ways.
Not sure about Part B though... I don't even understand what it's asking.

I misunderstood completely, don't take my answer into account xD
