Let U = {5, 10, 15, 20, 25, 30, 35, 40}

A = {5, 10, 15, 20}

B = {25, 30, 35, 40}

C = {10, 20, 30, 40}.

Find A ⋂ C.

See answer to previous question.

Here again, A∩C should have two elements.

A n C {10, 20}

To find the intersection of two sets, you need to identify the elements that are present in both sets. In this case, you want to find the intersection of sets A and C.

Set A = {5, 10, 15, 20}
Set C = {10, 20, 30, 40}

To find the intersection, you will look for the elements that are common to both sets. In this case, the elements 10 and 20 are present in both sets A and C.

Therefore, the intersection of sets A and C (A ⋂ C) is {10, 20}.
