Take {S,S,S,S} to be one letter....then you will have 8letters in which there are 4I's and 2P's....So arranging n things in which m are one type and n are of one type is n!/(m!)(n!)

hold on though, wouldn't we need to factor in that the S's can be in any particular order, so we have to avoid multiples, yeah?

So I wouldn't have to take into account the S's? But for the I's and the P's?

IMISSSSIPPI and MSSSSIIPIPI are two of the arrangements...here if you take a look, you will find all S's together but I's and P's may be all together or a few together and others seprated or all may be separated...So, I's and P's must be considered for arranging but not S's

OH! I see where this is going. But couldn't you also have ISSSSI and ISSSSI with just the S's rearranged?

if S's are rearranged the word looks the same but if I's and P's are rearranged, word changes and thats what the question is about..Find the different words formed by reaarrangement
