Aprofessors writes 24 discrete mathematics true/false questions. of the statements in these questions, 11 are true. if the questions can be positioned in any order, how many different correct answer keys are possible? (show work)

3. what is the output of the following statements? temporary object1; temporary object2("rectangle", 8.5, 5); temporary object3("circle", 6, 0); temporary object4("cylinder", 6, 3.5); cout < < fixed < < showpoint < < setprecision(2); object1.print(); object2.print(); object3.print(); object4.print(); object1.set("sphere", 4.5, 0); object1.print();
