Question

Could you assist me with part c? I'm finding it challenging to grasp the concept involved in this problem. If possible, could you provide a visual explanation to enhance my understanding? Additionally, please note that this problem requires a solution in the form of a state diagram. To clarify, my current focus is solely on part c.

1.4 Each of the following languages is the intersection of two simpler languages. In
each part, construct DFAs for the simpler languages, then combine them using the
construction discussed in footnote 3
to give the state diagram of a DFA
for the language given. In all parts, Σ = {a, b}.
a. {w w has at least three a's and at least two b's}
Ab. {w w has exactly two a's and at least two b's}
c. {w w has an even number of a's and one or two b's}
