Urgent needed plz.1. find the number of permutations in the word autumn.120720540360

There are 6 letters in the word "autumn" so 
6! = 6*5*4*3*2*1 = 720
represents the number of ways to arrange the letters (order matters)

Note how there are two letter "u"s here which can't be told apart. If we could tell them apart, then the answer would be 720. However, we can't tell them apart. So we're doubly counting things. To undo this, we divide by 2

720/2 = 360



Final 360

The range would be 13 because you’re finding the difference
