Question 951518: Numbers that are palindromes read the same forward and backwards. 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.

You can put this solution on YOUR website!
You can't start a 3-digit number with +0+, so
the number of possible 3-digit number is:
+9%2A10%2A10++=+900+
As for the palindromes:
[ 0 n 0 ] is not a valid number ( n is any number )
so, there are +9%2A10%2A1+=+90+
I say the 3rd digit is +1+ because, once you choose the
1st digit, that determines the 3rd digit
The probability is:
+90%2F900+=+1%2F10+
Hope I got it
