How many different ways to arrange the word STATISTICAL if
a) the S's are together
for this one, i didnt know if I should just multiply the rest by 1 since the S's are the same or do 2x1 .
the rest is just the S's x 10 x 9!/3!2!2!
b) the S's not together
when i get my answer from part a , i'm gonna find the total possibilities of arrange the word which is 11!/3!2!2!2! = 831600 then subtract that with answer part a which i hope will give me the S's not together
c) the two S's together and two 1's together
for this one, i was thinking of doing two cases; 1 for just the two s's then the other for two i's together then just add those two, but then now it doesnt make sense to me :S
