What is the number of 5-permutations of the multiset { 1, 2, 0.3}? Consider the multiset M={3.a, 4.b, 5.c of size 12. Find the number of 10-permutations of M. How many possibilities are there to place 7 non-attacking rooks on an 7 x 7 chessboard if 3 rooks are white, 2 rooks are blue and 2 rooks are red?
