Which of the following statements are valid?
Select one or more:
{1,2,3,4,5} n {1,4,8, 12} = {1, 2, 3, 4, 5, 8, 12}
O {1,3,5,7,9,11,.... } U {2, 4, 6, 8, 10, .... } = N
(a, b, c, d, e} n {a, e, i, o, u} = {a, e}
Let A = {1, 3, 5, 7, 9}, B = {2, 4, 6, 8} and C = {1,2,3,4}.
Then (AUB) = {1,2,3,4}
{ 1, 3, 5, 7, 9, 11, .…….
.
For any sets X, Y and Z, the equality (X n Y) u Z = (XU Y) N Z is valid
(Hint: You might use venn diagrams to help detemine if the equality is valid)
} U {2, 4, 6, 8, 10, . .}
= Ø
Let A = {1,3,5,7,9}, B = {2, 4, 6, 8} C = {1, 2, 3, 4).
Then (An B) UC = {1,2,3,4}
If U = {1, 2, 3, ...., 7, 8, 9} then {1,3,5,7,9}º = {2,4,6,8}

Your program should store the correct answers shown above in an array. It should ask the user to
enter the student's answers for each of the 20 questions, and the answers should be stored in another
array. After the student's answers have been entered, the program should display a message
indicating whether the student passed or failed the exam. (A student must correctly answer 15 of
the 20 questions to pass the exam.) It should then display the total number of correctly answered
questions, the total number of incorrectly answered questions, and a list showing the question
numbers of the incorrectly answered questions.
Input Validation: Only accept the letters A, B, C, or…
