These are the two initial DFAs, and I need to construct a DFA that recognizes the intersection of the two languages accepted by the given DFAs, using closure properties.
Here is the first DFA:
And here is the second DFA:
My question is: if in the first automaton there is a transition on symbol b from state q0 to a sink state q3, then in the intersection automaton, is the state pair (q3, q1) also a sink state? Is that correct? The intersection automaton I found is made up of 6 states.
