ill give you a hint
the number of digits in the number doesn't matter cause we're only looking at the last 2 digits. It would be the same if it was a 30 digit number
there are 100 possible outcomes for the last 2 digits (0-99)
10 of them are dubs (00, 11, 22)
5 of them are even dubs (00, 22, 44, 66, 88)
you came to the right conclusion. but im convinced it was on accident cause your math doesnt make sense.

>Possibility for the next 5 difits = 1 to 9 AND 0 = 10
>Therefore no of favourable outcome = 9× 10 to the power 5 × 10
>Possibility of dubs = (9 × 10 to the power 6 / 9 × 10 to the power 7)
i hope you understand that this is babble
