In this problem, it is said that u is the universal set of natural numbers less than 11.
00:04
We have been given a few sets, and using those, we need to determine a few more sets.
00:09
So first of all, we need to determine u.
00:11
Now, this is the set of all natural numbers less than 11.
00:15
The natural numbers start from 1, so we have 1, 2, 3, 4, 5, 6, 7, 8, 9, and 10.
00:23
These are all of the natural numbers less than 11.
00:26
Next we have b complement.
00:27
This will be the set of all elements which are in the universal set but which are not in the set b.
00:33
Now b has the elements 5, 4, 9, and 7.
00:36
So b complement will have the elements 1, 2, 3, 6, 8, and 10.
00:42
These are the elements in the universal set which are not in the set b.
00:47
Next we have c complement...
