You may assume the default difficulty is to beat a 6, so any roll of 7 and above counts as one success.
RAW p.386:
Quote:
When you roll the dice, you want to equal or exceed the difficulty number. If that number’s 7, you want to score a 7, 8, 9, or 10 on each die.

Rolling a 1 cancels one success. If you roll more 1s than successes, you botch.
RAW p. 393:
Quote:
Game-wise, every 1 you roll takes away one success from your roll. Think of this as "the rule of one." If your 1s cancel out your successes, you fail; roll three successes, roll three 1s, and you’re left right where you were before.
Assuming that you rolled even one success before the 1s cancel out all your successes, then your character simply fails.
But if you don’t roll any successes and you roll a 1, then you botch.

Rolling 10 gives one success (Not two, I had to remind myself of this one vs other WoD games).
RAW p.386:
Quote:
A roll of 10 is always a success unless there was no way you could have performed that task to begin with
RAW p.273:
Quote:
On rolls that determine the success of an activity related to that Trait specialty, the player counts every 10 rolled as two successes, not just one.
