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)?

B intersection C gives set which contains those elements which are in both sets B and C so what would be B ∩ C?

if we had Z={1,2,3,4} and Y={3,4,5} intersection of Z and Y would be {3,4} because 1 is only in Z 2 is only in Z 3 is in Z and Y 4 is in Z and Y 5 is only in Y so only 3 and 4 are in both sets

also set H={1,1,1,1,2,2,2,1,1,2,2,2} is exactly same set as H={1,2} because if same thing repeats it doesn't matter
