How many unique ways are there to arrange the letters in the word IRON?
You have 555 reindeer, Balthazar, Jebediah, Lancer, Quentin, and Ezekiel, and you want to have 444 fly your sleigh. You always have your reindeer fly in a single-file line. How many different ways can you arrange your reindeer?

Question 1: 24

Question 2: 120

Step-by-step explanation:

Question 1: to find the number of arrangements, you can do 4!, meaning you do 4x3x2x1.

Question 2: to find the number of arrangements in this situation, you use permutation, using the expression 5!/(5-4)!. To simplify this, it would simply be 5!, because 1! is 1. 5x4x3x2x1=120

i think is g(1)=-1.
