    Consider the following grammar:S -> aBAA ->aAE | EB ->bBC | b...
    C, D and F are the useless symbols in given grammar.
    After removal of useless symbol the grammar will be
    S -> aBA
    A -> aAE | E
    B -> b
    E -> eE | e
    Then AÃ E is the only production which is not according to GNF.

    Identifying the Violation of Greibach Normal Form

    To determine the number of productions that violate the rules of Greibach Normal Form in the given grammar after removal of useless symbols, we need to consider the following rules of Greibach Normal Form:
    1. Each production should have a single non-terminal as the leftmost symbol.
    2. Each production should have a terminal as the second symbol.
    3. Each production should have a string of terminals and non-terminals following the second symbol.

    Analysis of the given grammar

    After removing useless symbols, the grammar becomes:
    S -> aB
    A -> aAE | E
    B -> bBC
    C -> cCD
    D -> aD
    E -> eE | eF
    F -> SeF

    Evaluating the productions

    1. S -> aB (violates GNF rule as 'a' is a terminal but not the second symbol)
    2. A -> aAE | E (satisfies GNF rules)
    3. B -> bBC (satisfies GNF rules)
    4. C -> cCD (satisfies GNF rules)
    5. D -> aD (satisfies GNF rules)
    6. E -> eE | eF (satisfies GNF rules)
    7. F -> SeF (satisfies GNF rules)

    Conclusion

    Out of the given productions, only the production S -> aB violates the rules of Greibach Normal Form. Thus, there is only 1 production that violates the rules of GNF in the given grammar.
