How many ways can the letters of the word probability be arranged?

Answer 1

There are 11 letters. But 2 letters repeat; the i and b.

The i occurs 2 times, as does the b.

Therefore, the total number of ways to arrange PROBABILITY is 11!/(2!2!)=9,979,200 ways

[I'm not the user who wrote this answer, but I am one "editing" it and writing this in the "[,]" things. But really, I just have a question. Can you say "11!/(2!2!)=9,979,200 ways" in a simpler way because I don't understand it (I am not an adult :) ). Please change this answer soon!]

Answer 2

نقسم عدد الحروف فكتوريال على عدد ال وجود كل حرف بالكلمه فكتوريال حيصير 11 فكتوريال على 2 في 2 فكتوريال لان حرف b ,i متكررات مرتين
