How many times you can rearrange the letter present?

Answer 1

The number of ways to rearrange the letters of a word depends on the total number of letters and any repeating letters. For a word with ( n ) letters, the formula to calculate the number of distinct arrangements is ( \frac{n!}{p_1! \times p_2! \times \ldots \times p_k!} ), where ( p_1, p_2, \ldots, p_k ) are the frequencies of each repeating letter. For example, the word "letter" has 6 letters with 't' and 'e' repeating, resulting in ( \frac{6!}{2! \times 2!} = 180 ) distinct arrangements.
