 Hi and welcome to the session, let us discuss the following question it says, make correct statements by filling in the symbol subset or not the subset in the blank. Now this symbol represents that the first set is a subset of the other set and this symbol states that it is not a subset. If every element of this set is also an element of this set then we say that this is a subset of this. Now we need to fill in all these blanks with these symbols. Now let us do the first part, says the elements of this set are 2, 3 and 4 and the elements of this set are 1, 2, 3, 4, 5. 2, 3, 4 are present in this set also so we will say that this is a subset of this set whereas A, B, C all the elements are not the subset of this. Only B and C are present in it but A is not present so we will say that it's not a subset. So simply just think that whether all the elements are present in the other set or not and if they are it will be a subset and if they are not then it will not be a subset. Now X is to X is a student of class 11th of your school. X is to X is a student of your class. So your school has how many students? A number of students but your class have a limited number of students. So all the students of class 11th are not in your class so we will say that it's not a subset of the other set. So you need to think about each and everything and then tell whether they are the subset or not. But if I change this from class to school then what will be your answer? All the students of class 11th are the students of your school isn't it? So will your answer get changed? Yes. So it will get changed to that it belongs it is a subset of the other set. Proceeding on further now we have here X is to X is a circle in a plane and X is to X is a circle in the same plane with radius one unit. So there can be a circle with radius more than one unit. So will it be a subset of this set? No. So we will say that it's not a subset. X is to X is a triangle in a plane and X is to X is a rectangle so definitely it's not a subset again. X is to X an equilateral triangle and X is to X is a triangle in the same plane. Equilateral triangle is a form of triangle only so we can say that this is a subset of this set. So last thing to be answered here is X is to X is an even natural number. X is to X is an integer. Integers consist all the even odd natural number right? So we will say that this is a subset. So in this question you must know what does this symbol means and what does this symbol means and you can easily write down the answers. I hope you enjoyed the session. Bye for now.
