Answer 1

Answer:

• Given sets:

ㅤ

A = {x : x € R and 1 < x ≤ 6}

B = {x : x € R and 6 < x < 10}

ㅤ

(i) AUB.

(ii) A∩B.

(iii) A-B.

(iv) B-A.

ㅤ

We know that,

• R = Real number,
• U = Union of two sets,
• ∩ = Intersection of two sets,
• {} = Braces,
• € = Belongs to.
• Ø = Empty set.

ㅤ

A = {2,3,4,5,6}

B = {7,8,9}

ㅤ

(i) AUB = {2,3,4,5,6} U {7,8,9} = {2,3,4,5,6,7,8,9}

(ii) A∩B = {2,3,4,5,6} ∩ {7,8,9} = {} = ∅

(iii) A-B = {2,3,4,5,6} - {7,8,9} = {2,3,4,5,6} = A

(iv) B-A = {7,8,9} - {2,3,4,5,6} = {7,8,9} = B
