Revision on Sets / Ulangkaji Sets (KSSM Maths F4)

What type of set is denoted as either { } or ∅?

Manakah jenis set yang berikut ditulis sebagai { } atau ∅?

• Superset

• Disjointed Set

• Empty (or Null) Set

  Set kosong atau null set

• Subset

A = {x : x is a letter in the word SEAT}

B = {x : x is a letter in the word TASTE}

Determine if these two sets are equal or equivalent.

A = {x: x ialah huruf dalam perkataan SEAT}

B = {x: x ialah huruf dalam perkataan TASTE}

Tentukan sama ada dua set ini adalah sama.

• Not equal because SEAT has 4 letters and TASTE has 5 letters.

  Tidak sama kerana SEAT mempunyai 4 huruf dan TASTE mempunyai 5 huruf.

• Equivalent because they have the same letters

  Sama kerana mereka mempuntai huruf yang sama.

• Equal because each set has the same cardinality and the same letters.

  Sama kerana kedua-dua set ada bilangan unsur yang sama dan semua huruf yang sama.

• Not equal because both set has not same cardinality.

  Tidak sama kerana bilangan unsur dalam kedua-dua set tidak sama.

If A = {1, 3, 5, 7, 9} and B = {2, 3, 5, 7}, what is A ∪ B?

Jika A = {1, 3, 5, 7, 9} dan B = {2, 3, 5, 7}, apakah A ∪ B?

• {3, 5, 7}

• {2, 3, 5, 7}

• {2, 3, 5, 7, 9}

• {1, 2, 3, 5, 7, 9}

If A = {1, 3, 5, 7, 9} and B = {2, 3, 5, 7}, what is A ∩ B?

Jika A = {1, 3, 5, 7, 9} dan B = {2, 3, 5, 7}, apakah A ∩ B?

• {3, 5, 7}

• {2, 3, 5, 7}

• {2, 3, 5, 7, 9}

• {1, 2, 3, 5, 7, 9}

The Universal Set = { -4, -3, -2, -1, 0, 1, 2, 3 ,4} and A = {0}.

What is the complement of A?

• {-4, -3, -2, -1, 0, 1, 2, 3}

• {-3, -2, -1, 1, 2, 3}

• {-4, -3, -2, -1, 1, 2, 3, 4}

• {-4, -3, -2, -1, 1, 2, 3}
