Since many formulas and requirements here cannot be posted here, I can only put them in the link and only need to answer 2 questions. Just copy the link into your browser to see the requirements and questions inside.

Please use the algorithm of discrete structure to answer and calculate the 2 questions in the link. thanks.

You only need to answer 2 questions, and you don't need to answer other unrelated questions.
