There are 3 vowels (A, U, A) which can be arranged in \[\frac{3!}{2!}\] ways Now, no. of ways in which all the vowels come together (considering all the vowels as a single unit) \[=6!\times \frac{3!}{2!}\] \[\therefore \] Required no. of ways in which all the vowels do not come together \[=\frac{8!}{2!}-\frac{6!3!}{2!}\] \[=20160-2160=18000\]You need to login to perform this action.
