Apalindrome is a number that reads the same forward and backward. for example. 2442 and 111 are palindromes. if 5-digit palindromes are formed using one or more of the digits, 1, 2, 3, how many such palindromes are possible? a) 12b) 15c) 18d) 24e) 27

(E) 27

Step-by-step explanation:

Let the 5 digit palindrome be PQRQP

Since each digit is chosen from 1,2,3 therefore

P can either be 1,2 or 3 which gives us 3 options.

Q can also either be 1,2 or 3 which gives us 3 options

R can either be 1,2 or 3 which also gives us 3 options

So we have 3^3 = 3*3*3

= 27

This means 27 palindromes are possible if they are formed using one or more of the digits, 1, 2, 3.
