Question

find the union and intersation of the following A={2,3,5,7,9}B={1,2,3,4,5} ​

Answer 1

Answer:

A={2,3,5,7,9}

B={1,2,3,4,5}

A ∪ B = {1,2,3,4,5,7,9}

A ∩ B = {2,3,5}

Union represents all the elements of both sets put together.

Intersection denotes the elements that are common to both sets.
