Answer:

In mathematics, the intersection A ∩ B of two sets A and B is the set that contains all elements of A that also belong to B (or equivalently, all elements of B that also belong to A), but no other elements. For explanation of the symbols used in this article, refer to the table of mathematical symbols.

We just saw how to join two sets using "Union" (and the symbol ∪). There is also "Intersection" which means "has to be in both". Think "where do they overlap?". The Intersection symbol is an upside down "U" like this: ∩

Please mark me as brainlyist

it is this because it says to shade b and c so i did that but also it says to shade u and it says u is n and n is a so you shade b c and a

Answer:

Figure 3 shows the shaded area for [tex](C\cup B)\cap A'[/tex].

Step-by-step explanation:

It is given that A, B and C are three different sets. U is the universal set.

We need to find the shaded area for [tex](C\cup B)\cap A'[/tex].

Here,

[tex]\cup = Union[/tex]

[tex]\cap = Intersection[/tex]

Now,

[tex](C\cup B)[/tex] means either C or B.              .... (1)

[tex]A'=U-A[/tex] means all part U except A.           .... (2)

The shaded region for both conditions is shown below.

[tex](C\cup B)\cap A'[/tex] is intersection of (1) and (2).

So, the final shaded reason is shown in figure 3.
