Number of Elements of finite sets A B 1 2 3 4 OK

Number of Elements of finite sets C A 2 1 4 7 5 6 8 3 OK B

Number of Elements of finite sets A B A={2,3,4,5,6 } , n(A) = 5 2 1 3 B={1,3,5,7} , n(B) = 4 4 5 7 6 OK

Number of Elements of finite sets A B 3 A={2,4,6,8,9 } , n(A) = 5 2 4 6 5 B={3,4,5,6,7,8,} , n(B) = 6 9 7 8 OK

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)=80 , n(A)= 21 , n(B) =36 33 B A 26 11 10 OK

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)=120, n(A)= 35 , n(B) =53 41 B A 26 9 44 OK GSP-g6

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

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

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

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

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

Exemple A 35 B 20 8 37 solution OK

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

Exemple 35 B A 20 8 37 solution OK

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

Exemple 35 A B 20 8 37 solution OK
