Question

If A = { 1, 3, 5, 7, 9} and B = { 2, 3, 4,5,7}, then find AΔB .

Answer 1

Given:-

• A = {1 ,3, 5, 7, 9}

• B = {2 ,3, 4, 5, 7}

To find:-

• The value of A Δ B

Solution & Explanation:-

Firstly we have to combine the both sets then you will get answer,

A = {1, 3, 5, 7, 9}

B = {2, 3, 4, 5, 7}

then, combine both sets

According to given question we have to find the value of "A Δ B"

⇒A = {1, 3, 5, 7, 9} ∪ B = {2, 3, 4, 5, 7}

⇒A ∪ B = {1, 3, 5, 7, 9} ∪ {2, 3, 4, 5, 7}

⇒A ∪ B = {1, 2, 3, 4, 5, 7 , 9}

therefore, The value of A Δ B = {1, 2, 3, 4, 5, 7 , 9}
