Sign In
The symbol â‹‚ indicates the intersection of two sets.
A â‹‚ B={4}
Since we have the symbol â‹‚, 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 â‹‚ B&={ 4}
