our physics club has $20$ members, among which we have $3$ officers: president, vice president, and treasurer. however, one member, alex, hates another member, bob. how many ways can we fill the offices if alex refuses to serve as an officer if bob is also an officer? (no person is allowed to hold more than one office.)
