Answer:
There are 181,440 ways.
Step-by-step explanation:
Given the word CHRISTMAS
In the word "Christmas" there are 9 letters.
Also take note, the letter "s" is repeated twice.
Hence, the number of ways is given by; no of ways = n!/m!
Where, n = 9, m = 2
no of ways = 9 *8*7*6*5*4*2*1/2*1
no of ways = 9*8*7*6*5*4*3
no of ways = 181,440.
Therefore, the number of unique ways that the letters in the word can be arranged is 181,440.
