20. 6) The diagram shows the set U , A , B and C
It is given that n(U)=110 , n(A)=35 , n(B) =26 , n(C) = 39 A B 11 7 8 5 3 11 20 45 C OK

21. The diagram shows the set U , A and B
Exemple
The diagram shows the set U , A and B
It is given that n(U)=100 , n(A)= 28 , n(B) =45
100-65 35 B A 20
28-8 8 37
45-8
B – A =
A – B = OK

22. Exemple 35 B A 20 8 37
solution
n(A – B) = 28 – 8 = 20 OK

23. Exemple 35 B A 20 8 37
solution
n(B – A) = 45 – 8 = 37 OK

24. The diagram shows the set U , A and B
Exemple
The diagram shows the set U , A and B A 35 B 20 37 8 = 65 + + OK

25. Exemple A 35 B 20 8 37
solution OK

26. The diagram shows the set U , A and B
Exemple
The diagram shows the set U , A and B A 35 B 37 8 20 + = 72 OK

27. Exemple 35 B A 20 8 37
solution OK

28. The diagram shows the set U , A and B
Exemple
The diagram shows the set U , A and B 35 B A 20 8 37 OK
