Question

Let A = {2, 3, 4, 6}, B = {5, 7, 8}, C = {2, 7, 8, 9}, find: (a) A – B (b) B – A (c) C – A (d) A – C

Answer 1

Answer:

Suppose that A={2, 4, 6}, B={2, 6}, C={4, 6}, and D={4, 6, 8}. ... c c r t rs r rs ? f f. Every set is a subset of itself. B is a subset of A. C is a ... Let A={a, b, c, d, e} and B={a, b, c, d, e, , g, h

Answer 2

Answer:

a) ={2,3,4,6} - {5,7,8}

={2,3,4,5,6,7,8}

b) ={5,7,8} - {2,3,4,6}

={2,3,4,5,6,7,8}

c) ={2,7,8,9} - {2,3,4,6}

={3,4,6,7,8,9}

d) ={2,3,4,6} - {2,7,8,9}

={3,4,6,7,8,9}
