Question

Solve (i)Let U = {x : x ∈ N, x ≤ 9}; A = {x : x is an even number, 0 < x < 10}; B = {2, 3, 5, 7}. Write the set (A U B)’. (ii) If X= { a, b, c, d } and Y = { f, b, d, g}, find: (a) X – Y (b) Y – X​

Answer 1

Step-by-step explanation:

Solution:- Of ( 1 )

Let U = (x:x EN, x ≤ 9); A = (x:x is an even number, 0<x< 10); B = {2, 3, 5, 7}

U = {1, 2, 3, 4, 5, 6, 7, 8, 9)

A = {(2, 4, 6, 8]

AUB=(2, 3, 4, 5, 6, 7, 8)

(A U B)' = {1, 9)
