A palindrome 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, and 3, how many such palindromes are possible?

    27

    Step-by-step explanation:

    Let the 5 digit palindrome formed from 1,2,3,4,5 be represented as XYZXY

    Possible outcomes of X are 1,2,3 which give 3 possible outcomes

    Possible outcomes of Y are 1,2,3 which also gives 3 possible outcomes

    Possible outcomes of Z are 1,2,3 which will give 3 possible outcomes.

    The total possible outcome = 3*3*3

    = 27
