Exercise 16 Page 218

The symbol ⋂ indicates the intersection of two sets.

A ⋂ B={4}

Practice makes perfect

Since we have the symbol ⋂, we are looking for the intersection of the given sets.

First, we will write B in roster form. B={0, 2, 4, 6, 8} An intersection of two sets is the set that contains elements that are common in both sets. An element is in the intersection of A and B if it belongs to A and to B at the same time. A&={1, 3, 4} B&={0, 2, 4, 6, 8} A ⋂ B&={ 4}
