1. Nyatakan bilangan subset bagi P = {B, A, I, K}. (b) Diberi ξ = {x : x ialah integer dan 21 < x < 30}
State the number of subsets of P = {B, A, I, K}. dan P = {x : x ialah nombor dengan keadaan hasil
A 4 C 12 tambah digit-digitnya ialah nombor ganjil}.
B 8 D 16 Given ξ = {x : x is an integer and 21 < x < 30} and
P = {x : x is a number such that the sum of its digits is
an odd number}.
