- This should help students have some clarity regarding shading 'intersections' and 'unions' for set A, B, A' and B'.
The trick is to always shade first part of the question i.e. in A⋂B shade A first, then with different color B. Finally area that intersects/overlaps is the answer.

Nahhh no way ur making memes in math channel
😂😂
If I like your comment then the number will no longer be the holy no. 69, tell me what should I do?
AuB' y shading the intersection
Yes they did it wrong
cuz it includes the full of A and the full of Not B
U= "or" which means to add ∩ = and means to find common ,A U B' = A or not B because there's an or we add A and anything not B, if it was A ∩ B' , "A and not B" we find the common shaded regions in the two and only mark that
Because, A ∪ B' = { x | x ∈ A or x ∈ B' }
= (A - B) ∪ (A ∩ B) ∪ B'
Proof:
LHS = A ∪ B'
= ( A ∩ U ) ∪ B' ----- (• using Law of U)
= ( A ∩ (B' ∪ B) ) ∪ B' ----- (• using Complement law)
= [ (A ∩ B') ∪ (A ∩ B) ] ∪ B'
= [ (A - B) ∪ (A ∩ B) ] ∪ B' ------ [• (A ∩ B') = (A - B) ]
= ( A - B) ∪ (A ∩ B) ∪ B'
= RHS
Because, A ∪ B' = (A - B) ∪ (A ∩ B) ∪ B'
⇒(A - B), (A ∩ B) and B' must be shaded to show A ∪ B'
Proof: Solving LHS
= A ∪ B'
= [ A ∩ U ] ∪ B'
= [ A ∩ (B' ∪ B) ] ∪ B'
= [ (A ∩ B') ∪ (A ∩ B) ] ∪ B'
= [ (A - B) ∪ (A ∩ B) ] ∪ B'
= (A - B) ∪ (A ∩ B) ∪ B'
= RHS
Showed this to my Younger brother
Now he fears what he's going to be doing in college.....
This is literally for 7th grade wtf

Isn’t the last one wrong? The intersection shouldn’t be shaded?
No, it's correct. The intersection should be shaded
as A ∪ B' = (A - B) ∪ (A ∩ B) ∪ B'
Write down the A/B with the circles for better understandment
Enigliss op😂
I want to make an assignment of intersection how should I do
Can you show the diagram of the set of three numbers? ie Au (BnC)= (AuB)n(AuC)
Statistics Mutually Exclusive
what if the circle for AuB arent connect? is it an empty set?
Then you will shade both A nad B. But if it is intersection, you won't shade any of the sets
AuB' is wrong... Intersection should not be shaded
no, its correct
I don't understand 😕 😐 😒 😑
Understand it properly until u know it bud u'll get there
intersection is the common which is ( upside down u ) , and the union which is ( u ) is both sets together , and the apostrophe is like x bar which is a compliment , when the bar is on B it means u have to insert everything but B
if the two sets are bar what is the solution?
jesus
really shouldnt have colored in full sample space in last one
is the shaded part the place where to answer?
yes ofc obviously 💯 that is only he is saying/showing
😢.... Which country is this math.

@@RayhaanKhan-mu4qu.
In A union Bcompliment u won't colour aunion b
You have to colour a union b (A∪B) as well in A union B complement ( A∪B' )
@@aryan.nayak87why?
Maybe talk
ez
The tutor should have explained orally.
Very good🎉🎉🎉🎉
"Yes, you are right. The third and last ones were wrong.".
You are not right at A u B
he is, it's union set
no, its correct
