33:34 its not union it's universal , universal intersection with A gives A .

[@MagnetBrainsEducation]

You are absolutely correct! Union and intersection are two important concepts in mathematics and it is great that you were able to identify that in our video. We are happy to offer these videos for free to help students learn more about mathematics.

What is difference b/w universal and union set ??

[@harshdeeppatel3998]

The universal set is a set which consists of all the elements or objects, including its own elements. It is represented by just a symbol ‘U’. But the union of sets is an operation performed on two sets, say A and B, which results in a set that has all elements belonging either to set A and set B or both. The operand of union of set is given by ‘∪’. For example, Set A = {a,b,c} and set B={c,d,e} and U={1,2}. Therefore, the universal set for set A, B and U itself will be; U ={a,b,c,d,e,1,2} You can see, U is also a set which collectively shows all the elements of A, B and of itself. Now, the union of set A and B is given by: A∪B = {a,b,c,d,e}

difference set A-b B-a A intersection b It is mutually disjoint set

[@ishu_dwivedi]

Yes it's a mutually disjoint set...

[@GauravSharma-py8if]

"Subtract" is the word. Though the obsolete word "substract" did exist, any occurrence you see these days is most likely just a common mistake, formed by analogy either with "abstract" or with other languages whose corresponding words do have two 's's

[@Borntoraceandwin]

Thankyou dear🥰 for making us remember the fact. I was known to this but had forgotten the fact. If everybody posts such useful comments, then studies will become far more easy. Education should be available even in the inner depths of comment section 😍

Sir jo union hoga vo universal set ki tarah kam karega na??

[@MagnetBrainsEducation]

Thank you for your question! The universal set is the set of all things being considered, while the union is the set of all things in both sets being considered. So, in short, the union will always be a subset of the universal set.
