10 Judo Throws & 20 Dojo Drills: Judo training drills to help kids master judo techniques

Matematika Diketahui S = {1, 2, 3, 4, 5, 6, 7), A = (x | x < 6, x bilangan asli), da B = {x|x < 8, x bilangan prima} a. Tentukan B-A b. Apakah B-A=A-B

Diketahui S = {1, 2, 3, 4, 5, 6, 7), A = (x | x < 6, x bilangan asli), da B = {x|x < 8, x bilangan prima} a. Tentukan B-A b. Apakah B-A=A-B

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

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

B = {2, 3, 5, 7}

a. B - A

Artinya, anggota di himpunan B yang tidak ada di himpunan A

B - A = {2, 3, 5, 7} - {1, 2, 3, 4, 5}

= {7}

b. B - A = A - B ?

B - A = {7}

A - B = {1, 2, 3, 4, 5} - {2, 3, 5, 7}

= {1, 4}

B - A ≠ A - B
