Hi,
number of four-letter arrangements, without repetition, from the set:
{D, S, U, X}  = 24 possible arrangements
How many arrangements have no vowels? without repetition, NONE

I can't make that huge tree diagram on here because it has 24
things in the last column of branches of the tree. However the
answer to the question is 0 because you can't have a 4-letter
arrangement with only 3 consonants without repeating one of the
3 consonants.
