What is a Finite Automata? For the given alphabet {a, b}, design a finite automata which accept any number of b’s followed by a single a (e.g., ba, bba, bbba, etc.). Neatly describe the initial state, accepting state, and transitions, if any. 2. What are the key differences between DFA and NFA? 3. Write a regular expression for a binary string (e.g., 0, 1, 01, 00, 11, 0101).

Question
1. What is a Finite Automata?
For the given alphabet {a, b}, design a finite automata which accept any number of b’s followed by a
single a (e.g., ba, bba, bbba, etc.). Neatly describe the initial state, accepting state, and transitions,
if any.
2. What are the key differences between DFA and NFA?
3. Write a regular expression for a binary string (e.g., 0, 1, 01, 00, 11, 0101).
Also, design a NFA for it. Clearly describe the ε transitions.
