Q. What is the total number of different 10-letter arrangements that can be formed using the letters in the word CHEESECAKE?Answer:
Count Letters: Count the number of each letter in CHEESECAKE: C=2, H=1, E=3, S=1, K=1, A=1, E=3 (already counted).
Calculate Total Factorial: Calculate the factorial of the total number of letters: 10! for the different arrangements if all letters were unique.
Divide by Repeating Factorials: Divide by the factorial of the number of times each letter repeats to correct for overcounting: divide by 2! for C and 3! for E.
Perform Calculation: Perform the calculation: 10!/(2!∗3!)=3,628,800/(2∗6)=3,628,800/12=302,400.
