Question: ( 5 pts ) Design a context - free grammar ( CFG ) that generates all strings over { a , b , c }

(5pts) Design a context-free grammar (CFG) that generates all strings over {a,b,c} that contain at least one 'a', one 'b', and one 'c'.
I. Define the rules of the CFG.
II. Provide a derivation for the string "abc".
III. Explain why the CFG does not generate the string "ab" or "bc".
