How many arrangements are there where no two vowels are next to each other?
The answer is: 457228800
I'm not getting the right answer for some reason... :-\

9 consonants and 5 vowels.
Arrangement for consonants = 9!, thereby we have 10 spaces to fit in the vowels, and they can be arranged in any manner. So arrangement for these : 10C5 X 5
Multiplying all : 9! X 10C5 X 5

What does " µ" symbol mean? I saw it in some questions..does it mean anything like sigma means standard deviation? are there any more weird symbols in S1 we should know about? What are the things given in the formula booklet for S1 that we shouldnt learn?

"µ" stands for the Greek letter, moew. Equivalent of the mean. You will use it in distributions most often.
