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
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

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?
Nah no wayy 😂😂😂😂😂😂
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

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
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'
@@πΣυφ-μ2ξbro LAST 2 SUMS ARE WRONG BRUH. AUB' = U - AUB ❤
@kidsknowledge2223 it is correct only as the said A union B complement not A intersection B complement
@@Aarush_789 oh ty
Write down the A/B with the circles for better understandment
Enigliss op😂
Take an English class for better "understandment"
AuB' is wrong... Intersection should not be shaded
no, its correct
A ∩ A'=?
It will be (PHI) (Null set)
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
Statistics Mutually Exclusive
as a 7th grader, this actually helped a ton
is the shaded part the place where to answer?
yes ofc obviously 💯 that is only he is saying/showing
if the two sets are bar what is the solution?
jesus
😢.... Which country is this math.
india
What's the name of the song ???
really shouldnt have colored in full sample space in last one
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
Can you show the diagram of the set of three numbers? ie Au (BnC)= (AuB)n(AuC)
In A union Bcompliment u won't colour aunion b
@@πΣυφ-μ2ξwhy?
I want to make an assignment of intersection how should I do
My lawn is a Venn Diagram

The tutor should have explained orally.
"Yes, you are right. The third and last ones were wrong.".
Today is paper
Wrong
tq🎉❤
Maybe talk
Last wala wrong hai
Super 🌈😂
You are not right at A u B
he is, it's union set
no, its correct
The last one is eating my mind

Very good🎉🎉🎉🎉
