D Lengkapkan setiap yang berikut dengan menggunakan simbol  atau . TP 2 ARAS R
Complete each of the following by using the symbol  or .

Contoh 1. B = {x : x ialah gandaan 2 dan 2. C = {x : x ialah nombor perdana
x , 30} yang kurang daripada 20}
A = {warna pelangi}
B = {x : x is a multiple of 2 and C = {x : x is a prime number less than
A = {colours of the rainbow} x , 30} 20}

(i) Merah / Red  A
(i) 12  B (i) 1  C
(ii) Putih / White  A
(ii) 21  B (ii) 2  C
(iii) Indigo / Indigo  A
(iii) 32  B (iii) 17  C

E Tentukan bilangan unsur dalam setiap set yang berikut. TP 2 ARAS R
Determine the number of elements in each of the following sets.

Contoh 1. Q = {huruf dalam perkataan 2. R = {faktor bagi 18}
‘TRANSFORMASI’} R = {factors of 18}
P = {huruf dalam perkataan
Q = {letters in the word
‘MATEMATIK’} ‘TRANSFORMASI’} R = {1, 2, 3, 6, 9, 18}
P = {letters in the word ‘MATEMATIK’}
Q = {T, R, A, N, S, F, O, M, I} n(R) = 6
P = {M, A, T, E, I, K}
n(Q) = 9
n(P) = 6 Terdapat 6 unsur.
Has 6 elements.

F Tentukan sama ada setiap pasangan set yang berikut ialah set sama atau bukan. TP 2 ARAS R
Determine whether each of the following pairs of sets are equal.

Contoh 1. X = {huruf dalam perkataan 2. P = {x : x ialah kuasa dua sempurna
‘EARTH’} dan x , 30}
K = {huruf dalam perkataan ‘MANIS’} Y = {huruf dalam perkataan Q = {4, 9, 16, 25}
L = {huruf dalam perkataan ‘MASIN’} ‘HEART’}
P = {x : x is a perfect square and
K = {letters in the word ‘MANIS’} x , 30}
L = {letters in the word ‘MASIN’} Q = {4, 9, 16, 25}
X = {letters in the word ‘EARTH’}
Y = {letters in the word ‘HEART’}
K = {M, A, N, I, S}
L = {M, A, S, I, N} X = {E, A, R, T, H} P = {1, 4, 9, 16, 25}
Y = {H, E, A, R, T} Q = {4, 9, 16, 25}
K = L
X = Y P ≠ Q
