Final answer:
The number of permutations that can be made using all the letters in a word can be calculated using the formula for factorial.
Step-by-step explanation:
The number of permutations that can be made using all the letters in a word can be calculated using the formula for factorial.
The factorial of a number is the product of all positive integers less than or equal to that number. So, for example, if the word has 4 letters, the number of permutations would be 4! = 4 × 3 × 2 × 1 = 24.
