I nderstand people thumbing donw fail rolls....but a comment with out a roll? Thats just showing hate to someone who is respecting this asshole who rolled trips.
It isn't.
The first number is random, and you have 2 others to fill (4xx, 5xx, 6xx, etc.)
As you have 10 digits in the decimal system, The Odds to roll the same number for x two times is 1:10², which equals 1:100.
You forgot that it doesn' t matter if you roll 555, 666, or 444. Therefore, WHICH trips you roll is irrelevant. If you want to roll a certain 3-digit-number, THEN the odds are 1:1000 as you have 10^(-3).
