<span>In this problem, we will use the combination
since the order does not matter but the flower can only be selected once. From the
given, we have a total of 11 flower and 9 flowerpots, to get the number of
possible combinations, we can write is at 11C9 or 11! / {9! (11-9)!}. The total
number of possible combinations is 55</span>
