G. BEZA ANTARA GAMBARAJAH VENN YANG “ADA DOT” DAN “TANPA DOT”.
DIFFERENT BETWEEN THE VENN DIAGRAM “WITH DOT” AND “WITHOUT DOT”.

1. Berdasarkan set di bawah, nyatakan bilangan unsur bagi kedua-dua gambarajah.
According to the set below, state the number of elements for both diagram.
a) P Q b) P Q
. 8 . 12 4
. 2 . 17 . 21 . 3 9 5
. 4 3 2
. 9 . 6 . 7 1
6
. 11 . 10 R R
. 5

i) n(P) i) n(P)

ii) n(P Q’) ii) n(P’ Q)

iii) n(P R Q’) iii) n(P R Q)’

2. Selesaikan masalah berikut.
Solve the following problems.

a) b) Gambarajah Venn menunjukkan set semesta,
ξ A ξ = {Pelajar tingkatan empat}, set H = {Pelajar
3 B C yang menyukai sejarah} dan set S = { Pelajar
7 4 yang menyukai Sains}.
11 x 2 Venn diagram shows the universal set , ξ ={Form four
students}, set H = {Students likes history} and set S =
{ students likes science }

Diberi bahawa n (A') = n ( B C' ), cari nilai x. ξ H S
Given that n (A') = n ( B C' ), find the value of x.

Diberi n(ξ)=130, n(H)=65, n(S)=80 dan
n(H S)=32. Cari bilangan pelajar yang
tidak menyukai kedua-dua subjek.
Given n(ξ)=130, n(H)=65, n(S)=80 and n(H S)=32.
Find the number of students neither likes both subjects.
