Sagot :
If a palindrome is a string of characters the reads the same backward as it does forwards then there are 120 such palindromes after solving through permutations.
Given that a palindrome is a string of characters the reads the same backwards as it does forwards.
We are required to find the number of 6 letter palindromes.
Permutations is basically finding how many ways in which the some numbers or things can be arranged. It is expressed as [tex]nP_{r}[/tex]=n!/(n-r)!.
If there are 6 letters then in a palindrome 3 alphabets are used here to form a 6 letter word.
=6[tex]P_{3}[/tex]
=6!/(6-3)!
=6*5*4*3!/3!
=120 palindromes.
Hence if a palindrome is a string of characters the reads the same backward as it does forwards then there are 120 such palindromes.
