Question

2) write union and intersection of following sets a = (123) b = (2 3 4​

Answer 1

Answer:

Union of a and b is {1, 2, 3, 4}

Intersection of and b is {2, 3}

Step-by-step explanation:

a = {1, 2, 3} , b = {2, 3, 4}

a ∪ b = {1, 2, 3} ∪ {2, 3, 4}

= {1, 2, 3, 4}

a∩ b = {1, 2, 3} ∩ {2, 3, 4}

 = {2, 3}
