Question

1.Diketahui: n(A)=28, n(B)=19, n(ANB)=12, berapa n(AUB)?

2.Diketahui n(A)=21, n(B)=18, n(AUB)=32, berapa n(ANB)?

3.Diketahui n(B)=18, n(A)=13, jika ACB, maka n(AUB)?

4.Diketahui n(A)=16, n(B)=19 dan A//B, berapa n(AUB)?

5.Diketahui n(S)-100, n(A)=50, n(ANB)=10, n(AUB)'=20. Berapa n(B)?​

Answer 1

Verified answer

a. n(A U B)= 28+19−12 = 35

b. n(A n B)= 21 + 18−32 = 7

c. n(A U B) = n(B) = 18

d. n(A U B)= 16+19 = 35
