Q. What is the total number of different 12-letter arrangements that can be formed using the letters in the word CIVILIZATION?Answer:
Count Letters and Frequencies: Determine the total number of letters and the frequency of each letter in the word CIVILIZATION.CIVILIZATION has 12 letters in total.The frequency of each letter is as follows:C−1, I−4, V−1, L−1, Z−1, A−1, T−1, O−1, N−1.
Calculate Total Arrangements: Calculate the total number of arrangements using the formula for permutations of a multiset:The formula is n!/(n1!∗n2!∗…∗nk!), where n is the total number of items to arrange, and n1,n2,…,nk are the frequencies of each distinct item.For CIVILIZATION, this is 12!/(1!∗4!∗1!∗1!∗1!∗1!∗1!∗1!∗1!).
Evaluate Factorial Expressions: Evaluate the factorial expressions and perform the division.12!=479,001,600 (This is the number of ways to arrange 12 distinct letters.)4!=24 (This is the number of ways to arrange the four I's among themselves.)So, the total number of different arrangements is 24479,001,600.
Find Final Answer: Calculate the division to find the final answer. 479,001,600/24=19,958,400.
