i) place santa, how many possible squares can he appear in?
ii) now place the elves. There are 9 squares left and 3 elves. How many ways can you place them? (hint: Think of the n choose k function)
iii) multiply the numbers you came up with in (i) and (ii)
iv) voila

Alternatively how many ways can you choose 4 squares from the 10. Once you have the 4 chosen squares in how many ways can you pick one of those squares for the santa?
