The textbook (Webber) makes a grievous error in each and every drawing of a finite automaton. Were I grading this textbook, I’d be inclined to mark every such diagram as wrong! Arrows indicating transitions should touch states at both ends. They should leave a state and enter a state. The casual graphic treatment given in the textbook is just plain wrong. Some of you have taken this a step further and you have arrows and states floating in empty space with very little to indicate whence each arrow cometh and where it goeth. No, no, a thousand times NO!
