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

Yes, that's correct.
Thank you
all possible 3-digit numbers: 100, 101, ... , 999
there are 1000 of them

palindromes:
101, 202, 303, ...909 ---> 9 of those
111, 212, ... 919, --- 9 more
...
191, 292, ... 999 --- 9 of those
so there are 90 of them

prob(of your event) = 90/1000 = 9/100
