Calculate the following: B = 1, 3, 5) A = }1, 2, 3, 4, 5(8) If ( |(A × B) U (B x A)| .a |(A x B) (B x A)| .b (A x B)A(B x A) .c (10) The number of students majoring in mathematics in a college is 100. 88 sat for the Foundations of Mathematics course exam and 92 for the Discrete Mathematics exam, while 93 sat for the Calculus course exam. If the number of students who sat for the Foundations of Mathematics and Discrete Mathematics exams together is 85, and those who sat for the Discrete Mathematics and Calculus exams together is 90, and those who sat for the Foundations of Mathematics and Calculus exams together is 86 students, and 4 students were absent from all exams, use the formula in question (8) above to calculate the following: Number of students who took the Foundations of Mathematics and Discrete Mathematics tests. .a Number of students who took the Calculus test but did not take either the Foundations of Mathematics or Mathematics tests .b Intermittent. Number of students who attended only two out of the three tests. .c d Number of students who took all three tests.
