0 $begingroup$ Q: How many ways to form a word of 3 letters with English alphabet (repetition allowed)? A: 26^3 but shouldn't we account for the repeated alphabet? like aab, and aab is the same? Why isn't the question solved in the same way like "How many ways to arrange the word POOP" which the answer is 4!/(2!2!) permutations share | cite | improve this question edited Dec 22 '18 at 7:35 thikin hax asked Dec 22 '18 at 7:28 thikin hax thikin hax
