Question

18. Let U = {x : x € N and n s 8), A = {x: Xe N and 5 < x2 < 50; B = {x : x is a prime x < 8). Draw a Venn
diagram to show the relation between the given sets and list the elements of the following.
(1) А - В
(ii) B.
(iii) A​

Answer 1

Answer:

elements of set A: A = {x : -8 ≤ x < 8, x∈ N }

Answer 2

Answer:

1) A - B = {4,6}

2) B' = {1,4,6,8}

3) A' = {1,2,8}

Step-by-step explanation:

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

A = {3,4,5,6,7}

B = {2,3,5,7}

1) A - B = {4,6} [A-B = {x: x e A and x not e B}]

2) B' = {1,4,6,8} [elements present in U but not it B]

3) A' = {1,2,8} [elements present in U but not it A]

Hope this helps
