I think though, if 2 times out of 3 your neightbors dog is in the park it is wearing a sweater, the correct premise would be:
1. If my neighbour's dog is in the park, it's probably wearing a dog-sweater.
2. My neighbour's dog is in the park.
C. Therefore, my neighbour's dog is probably wearing a dog-sweater.
In a deductive argument, the premise must be true, or the argument breaks. The premise cannot be .6 likely true, or you cannot do deduction. Deduction only works on true premises, which is why Dr. Craig says that you ought to accept a premise as true if it is more plausible than its negation. This means that if it is .6, you need to accept at as 1 in order to proceed with deduction. This to me is a major problem.
He likely shies away from inductive arguments because of the problem you bring up with probabilities.
