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)?
so whats the answer ?
btw is the question multiple choice?
(B ∩ C) the answer i think would be is that the intersection is empty because none of the even intergers match in both B and C
if the question asked for odd intergers it would be 5,3, and 9
it asks for even numbers
i know but an example would be
B: {-1,0,2,4,6,7} C: {2,3,5,8} B ∩ C = {2}
