An individual's phone number contains seven digits, not including the area code, from the set A shown below.
A = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}

Set B represents the digits in Brent's phone number.
B = {5, 5, 5, 3, 0, 9, 9}

Set C represents the digits in Charlie's phone number.
C = {8, 6, 7, 5, 3, 0, 9}

How many even numbers are in the set ∼(B ∩ C)?

$\cap$ means intersection.  That is where there is an overlap between the sets.

$\cup$ means union.  That is everything from either set, just without duplication.

If $O=\{1,2,3\}$ and $P=\{2,3,4\}$ then:
$O\cup P=\{1,2,3,4\}$
$O\cap P=\{2,3\}$
