1) Sudharaka

2) MarkFL

3) soroban

4) veronica1999

Solution (from Sudharaka):

H - 2, A - 2, P - 2, Y - 2, O - 1, L - 1, I - 1, D - 1, S - 1

Number of letters in "Happy Holidays" = 13

Therefore the number of possible arrangements (A) = \(\dfrac{13!}{(2!)^4}\)

\[\therefore A \times \frac{503}{97297200}=\frac{13!}{(2!)^4}\times\frac{503}{97297200}=2012\]
