Question

math help ss below!

Answer 1

I believe it can be achieved by seating alternately.
tstststs
The first t is fixed so it will give permutation of 3, which is 3! = 6 ways
The permutation for s we get 4! = 24 ways
Total number should be 6*24
If the two seating's are counted same then we need to fix the position of t and count only the permutation of s. In this case we get 4! = 24 ways
I might be wrong
