Diketahui s = {×|×9 × bilangan asli } a = { 1 2 3 4 5 } dan b { bilangan prima dalam s}

Jawaban:

S = {1,2,3,4,5,6,7,8,9}

A = {1,2,3,4,5}

B = {2,3,5,7}

Jawab

a.

S = {1,2,3,4,5,6,7,8,9}

A' = {1,2,3,4,5}'

= {6,7,8,9}

B' = {2,3,5,7}'

= {1,6,8,9}

b. A ∩ B = {1,2,3,4,5} ∩ {2,3,5,7}

= {2,3,5}

c. A U B = {1,2,3,4,5} U {2,3,5,7}

= {1,2,3,4,5,7}

d. A – B = {1,2,3,4,5} – {2,3,5,7}

= {1,4}

e. (A ∩ B)' = {2,3,5}'

= {1,4,6,7,8,9}

f. (A U B)' = {1,2,3,4,5,7}'

= {6,8,9}
