Question

1. diberikan P = { 1,2,3,9,12,13 }
himpunan kelipatan 3 yang terdapat di P adalah...
2. jika K = { a,b,c } dan R = { 1,2,3,4 }
Maka n (R) - n(K) + 4 = ...

Answer 1

1. p = {3,9,12}
2. n(r) -n(K) +4 = 3 - 4 + 4 = 3

Answer 2

1. Kelipatan  tiga = {3,9,12}
2.n(R) = 4
   n(K) = 3
 4 - 3 + 4 = 5
