A = { Monday, Tuesday, Wednesday } . B

= { Tuesday, Friday, Saturday } .
What is An B?

The intersection of A and B, denoted by A n B, is the set of elements that are common to both A and B.

In this case, the common element between A and B is Tuesday.

Thus, A n B = { Tuesday }.

To find the intersection of two sets, A and B, denoted as A ∩ B, you need to find the elements that are common to both sets.

Given:
A = { Monday, Tuesday, Wednesday }
B = { Tuesday, Friday, Saturday }

To find A ∩ B, you need to determine the elements that are present in both sets A and B.

From the given sets, the element "Tuesday" is present in both A and B.

Therefore, A ∩ B = { Tuesday }
