I have a problem and I need to solve it, thank you from now.. An enormous amount of loot had been stolen from a store. The criminal (or criminals) took the heist away in a car. Three wellknown criminals, A, B, and C, were brought to the police station for questioning. The following facts were determined: 1) No one other than A,B, or C was involved in the robbery. 2) C never pulls a job with using A and (possibly others) as an accomplice. 3) B does not know how to drive Use truth table to determine if A is innocent or guilty?

This problem only makes sense if you meant 2) C never pulls a job without using A (and possibly others) as an accomplice. In that case, since "B does not know how to drive", B could not have done it alone. It could only be all three of ABC, or AB, or BC, or A alone, or C alone. Because "C never pulls a job without A", both BC" and "C alone" are impossible. That leaves "all three of ABC", or "AB", or "AC" or "A alone", all of which involve A.
