can you use probability control on a outsmart roll? thanks

Can't see any good reason why not...except that you'd never be able to prob your own Outsmart roll. Not unless your opponent figured out some way to Outwit you on your own turn. BUt the opponent's roll is ripe for probbing...assuming you've got line of fire to the character doing the Outwiting.

This is correct.
The roll is able to be prob'ed but it still falls under the Prob rules of your rolls on your turn and your opponents when its not your turn.

01001101 01100001 01110010 01100001 01110101 01100100

so if i try to outwit someone with outsmart, we do a roll off, he wins the roll, I can prob only my roll and not his?

Correct. With PC you can reroll your rolls on your turn. If it is your opponent's turn, your PC can only be used on your opponent's rolls.
