Suppose you have two math classes (math 1 and math 2)and two sciences courses (science 1 and science 2)that you must complete before your sophomore year in college.Assume your college is on a semester system and there are two semesters in each year.Suppose you are required to take exactly one of the science courses and exactly one of the math courses during your sophomore year.What is the event A of required math and science courses you could take the first semester of your sophomore year?
A)A = {math 1,math 2,science 1,science 2}
B)A = {math 1 and science 1,math 1 and science 2,math 2 and science 1,math 2 and science 2}
C)A = {1,1}
D)A = {1,2}

The event A represents the possible combinations of one math course and one science course in the first semester of sophomore year. This means that the event A can only include the pairs (math 1, science 1), (math 1, science 2), (math 2, science 1), or (math 2, science 2). Therefore, the best choice is B, which lists all possible pairs of math and science courses.
