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)?

hartnn · Answer

can u find B∩C ?

hartnn · Answer

its the elements common to B and C

anonymous · Answer

i only saw 1 common

hartnn · Answer

there are more, look carefully ....

hartnn · Answer

which did u get as common ?

anonymous · Answer

0

hba · Answer

It will be a null set

anonymous · Answer

Cause its evans and b has no more evans

hartnn · Answer

ok, look there is 5,3, and 9 also common....got it ?

anonymous · Answer

but its evens so the only one they have in common is 0

hba · Answer

B = {5, 5, 5, 3, 0, 9, 9} C = {8, 6, 7, 5, 3, 0, 9}
only even of set (B ∩ C)= {} dat is empty set

anonymous · Answer

0 3 and 5,9 are in common so we'll have the other elements 6,7,8 in the answer required

anonymous · Answer

so how many? because it says evens not odds too

hba · Answer

0 is neither odd nor even

hartnn · Answer

actually u need to first find B∩C, then negate it and then look for even numbers.

hba · Answer

The answer is a null set

anonymous · Answer

6 ,8 are the numbers and {6,8} is the answer

anonymous · Answer

0 is even 0-2-4-6-8 and such on

hba · Answer

{} dat is empty set

hartnn · Answer

and no, the answer is not null set @hba

hba · Answer

No 0 is not even

hba · Answer

The answer is null

anonymous · Answer

well i am confused now.. idk the answer

anonymous · Answer

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

anonymous · Answer

{6,8} is the answer @rebecca1233

anonymous · Answer

i hope....

anonymous · Answer

so 2 numbers

hartnn · Answer

nopes, its not 6,8

hba · Answer

NO  its   {}< ANswer

anonymous · Answer

thats what im saying.. im confused

hartnn · Answer

B∩C = {5,3,0,9}
~(B∩C) = {1,2,4,6,7,8}
so the nuber of even numbers are 4.

hartnn · Answer

'4' is final answer.

hba · Answer

I am sorry hartnn you are wrong

anonymous · Answer

how its askin for even ? not odd too

hartnn · Answer

i am certain that i am correct @hba

hba · Answer

It is only asking for even and the answer is null

hba · Answer

@hartnn  Unfortunately you are not

hartnn · Answer

its asking for even in THAT SET.

hba · Answer

Yeah So

hartnn · Answer

u first need to find THAT SET

hartnn · Answer

then count number of even numbers.

anonymous · Answer

its empty set

hba · Answer

Stupid its asking Even number when you do B∩C

hba · Answer

Yes its an empty set Rebecca

hartnn · Answer

then what is ~ sign for ??

hba · Answer

That means equivalent

hartnn · Answer

that means NOT or negation.

hba · Answer

B∩C= {5, 5, 5, 3, 0, 9, 9}∩{8, 6, 7, 5, 3, 0, 9} = {5,3,0,9}  < None of them is even so if we take out the Odd We get are answer which is  {}

hartnn · Answer

but u didn't get ~(B∩C).....

hba · Answer

You are wrong hartnn stop fighting

A = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}
B = {5, 5, 5, 3, 0, 9, 9}
C = {8, 6, 7, 5, 3, 0, 9}

   B ∩ C = {5, 3, 0,9}
∼(B ∩ C) = {1, 2, 4, 6, 7 , 8 }

even[∼(B ∩ C)] = {2, 4, 6, 8 }

count { even[∼(B ∩ C)] } =

thank you @UnkleRhaukus :)
