In this question we have to state whether the statements are true or false and we are given some set of statements in this question.
00:09
So first statement is that the set a, b, there is a set a b.
00:16
It is complement of the set given as cd and here the universal set is given as a b.
00:32
Ced.
00:34
Okay, so let's have a look at this part.
00:36
So consider two sets, capital a, capital b.
00:41
For a to be b complement, the set a must be equal to u minus b.
00:56
So this has to be two.
00:57
So as we can see the set a b is obtained after subtracting a, b, c d.
01:06
After subtracting the set cd from this universal set so this implies set a comma b is complement of complement of cd set okay so this statement is true completely true hence moving on to the second statement now the second statement said that says that a comma b set is only subset of the set a b.
01:49
Okay, so first of all writing the subsets of set a b.
01:55
So the subsets of set a b is set a, set a, set a, and a null set which is five.
02:10
So, these are the subsets of these are these all sets are subsets of ab.
02:19
Okay, so this implies the set ab is not the only subset of the given set ab...
