Answer 2

Answer with explanation:

Total number of Letters = T,U, V and W.

As you have to write down total number of arrangement of four letters,T,U, V and W, taken all at a time

= As Order of Arrangement of Alphabets is Important , so we can apply the Concept of Permutation or Principal of Counting , applying any of these will give you same result.

`= 4 ! \text{or}_(4)^(4)\textrm{P}=4 * 3 * 2 * 1 \text{or}=(4!)/((4-4)!)\\\\=24 \text{or} 4!=24`

→→Total number of orderings of these letters from left to right,including U T V W= 24 ways
