Q. What is the total number of different 8-letter arrangements that can be formed using the letters in the word ZIGGURAT?Answer:
Identify Unique Letters: Identify the unique letters and their frequencies in the word ZIGGURAT.ZIGGURAT contains the letters Z, I, G, U, R, A, T. The letter G appears twice, while all other letters appear once.
Calculate Total Arrangements: Calculate the total number of arrangements without considering the repetition of the letter G.The total number of arrangements of 8 letters is 8! (8 factorial), which is 8×7×6×5×4×3×2×1.
Calculate 8!: Calculate 8! to find the total number of arrangements without considering the repetition.8!=8×7×6×5×4×3×2×1=40,320
Adjust for Repetition: Adjust for the repetition of the letter G. Since the letter G is repeated twice, we need to divide the total number of arrangements by the number of arrangements of the repeated letters to avoid overcounting. The number of arrangements of 2 Gs is 2! (2 factorial), which is 2×1.
Calculate 2!: Calculate 2! to find the number of arrangements of the repeated Gs.2!=2×1=2
Divide Total Arrangements: Divide the total number of arrangements by the number of arrangements of the repeated Gs to find the correct total number of different arrangements.The correct total number of different 8-letter arrangements is 40,320÷2.
Evaluate Final Answer: Evaluate 40,320÷2 to find the final answer.40,320÷2=20,160
