Answer :
Final answer:
The total number of 5-letter words that can be formed using all the letters from the word 'BREAD' with repetition allowed is 3125. This is determined by using the permutations principle in combinatorics.
Explanation:
The subject of this problem involves understanding the principles of permutation and combination. In this specific case, we look at permutations, which is an arrangement of objects where the order is important. Since we are allowed to repeat letters, this means we will be using the rule of product. The word 'BREAD' has 5 distinct letters and we want to form a word with 5 characters, whereby the same letter can occur more than once.
Using the rule of product, since there are five choices (B, R, E, A, D) for each of the five positions in the word, we can calculate the total permutations as 5^5 = 3125. So, the correct answer is D - 3125.
