P = {x : x is a prime number, x < 20}. List the elements of P.
(Total for Question 2 is 2 marks)
3
A = {4, 8, 12, 16, 20} (the multiples of 4 up to 20). C = {2, 4, 6}. State, giving a reason, whether C is a subset of A.
(Total for Question 3 is 2 marks)
4
The universal set is xi = {1, 2, 3, ..., 20}. B is the set of multiples of 6 in xi, so B = {6, 12, 18}. State whether each of the following statements is true or false.
(i)12 is a member of B.(1)
(ii)20 is a member of B.(1)
(Total for Question 4 is 2 marks)
5
R = {even numbers from 1 to 9} and S = {odd numbers from 1 to 9}. Find R intersection S, giving a reason for your answer.
(Total for Question 5 is 2 marks)
6
The universal set is xi = {1, 2, 3, ..., 15}. A is the set of multiples of 3 in xi. B is the set of multiples of 5 in xi.
(a)Find n(A).(1)
(b)Find A intersection B.(2)
(Total for Question 6 is 3 marks)
7
In a group of 60 students, 34 like Football (F), 28 like Netball (N), and 10 like neither sport.
Figure (to be drawn): A two-circle Venn diagram inside a rectangle labelled xi. The circles are labelled F and N and overlap. Numeric values are not pre-filled; this diagram is to be completed as part of solving the question.
(a)Find n(F union N).(2)
(b)Find n(F intersection N).(2)
(c)Find the number of students who like Football only (Football but not Netball).(1)
(d)A student is chosen at random from the group of 60. Find the probability that the student likes Netball but not Football. Give your answer as a fraction in its simplest form.(2)
(Total for Question 7 is 7 marks)
8
In a survey of 100 students, the number studying French (F), German (G) and Spanish (S) is shown in the Venn diagram: the region where all three subjects overlap contains 5 students; the region for F and G only (not S) contains x students; the region for F and S only (not G) contains 8 students; the region for G and S only (not F) contains 6 students; the region for F only contains 20 students; the region for G only contains 15 students; the region for S only contains 2x students; and 10 students, outside all three circles, study none of the three languages.
Figure (to be drawn): A three-circle Venn diagram (circles F, G and S, all overlapping in the classic three-set arrangement) inside a rectangle labelled xi. Region values: all three = 5, F and G only = x, F and S only = 8, G and S only = 6, F only = 20, G only = 15, S only = 2x, outside all three circles = 10.
(a)Form an equation in x, and solve it to find the value of x.(3)
(b)Find the number of students who study Spanish.(3)
(c)Find the number of students who study at least two of the three languages.(2)
(d)A student is selected at random from the 100 students. Find the probability that the student studies exactly one of the three languages.(2)
(Total for Question 8 is 10 marks)
9
The Venn diagram shows two sets, A and B, inside the universal set xi. The region inside circle A but outside circle B is shaded. Which of the following correctly describes the shaded region?
Figure (to be drawn): A two-circle Venn diagram, circles A and B overlapping, inside a rectangle labelled xi. Only the part of circle A that does not overlap with circle B is shaded.
  • A) A intersection B
  • B) A union B
  • C) A intersection B'
  • D) A' intersection B
(Total for Question 9 is 1 mark)
10
Using the same two-circle Venn diagram as Question 9 (circles A and B inside universal set xi), write down the set notation for each region described below.
(a)The region where circles A and B overlap.(1)
(b)The region outside both circles.(1)
(c)The region inside circle B but not inside circle A.(1)
(Total for Question 10 is 3 marks)
11
The universal set is xi = {1, 2, 3, ..., 10}. A = {1, 2, 3, 4, 5}. B = {4, 5, 6, 7, 8}.
(a)Find (A union B)'.(2)
(b)Find A' intersection B', and state whether it is equal to your answer to part (a) (this checks De Morgan's law, (A union B)' = A' intersection B', for this example).(2)
(Total for Question 11 is 4 marks)
12
The universal set is xi = {1, 2, 3, ..., 12}. E = {even numbers in xi}. M = {multiples of 3 in xi}. Find the elements of E intersection M.
(Total for Question 12 is 2 marks)
