SOMEONE HELP ME,PLEASE :(

Directrix (directrix):

If all the letters were different, then the answer would be 11!. But there are repeated letters, the permuations of which have to be divided out. There are 4 of the letter i, 4 of the letter s, and 2 of the letter p. So, the number of 11-letter distinguishable permutations of Mississippi is the following: 11!/ (4! 4! 2!) = 34,650
