Question

Numbers that are palindromes read the same forward and backward. For​ example, 30203 is a​ five-digit palindrome. Of a single number is chosen randomly from the set of all​ two-digit numbers, find the probability that it will be palindromic.

Answer 1

`(1)/(10)`

Explanation:

Total number of two digit numbers are= 90

Palindrome numbers in two digit number= 11, 22,33,44,55,66,77,88,99.

Total Number of palindromic Numbers= 9

Probability of palindromic number=
`(Number of palindrome numbers)/(Total Number of outcomes)`

Probability of palindromic number=
`(9)/(90)`

Probability of palindromic number=
`(1)/(10)`

Hence, the correct answer is
`(1)/(10)`
