 Hello and welcome to the session. In this session we are going to discuss the following question which says that which of the following are statements? What are their truth values? Minus 2 plus 3 is equal to minus 1. A triangle has 3 sides. What is your age? We know that a given sentence is said to be a statement. It is either true or false. If the statement is true then its truth value is t. If the statement is false its truth value is f. With this key idea let us proceed with the solution. In this question we have to determine whether the given sentences are statements or not. Let us consider the first sentence. Minus 2 plus 3 is equal to minus 1. This is a statement because we can find whether it is true or false. Now we know that minus 2 plus 3 is equal to 1 and not minus 1 so minus 2 plus 3 equal to minus 1 is false. So we write the sentence minus 2 plus 3 equal to minus 1 is a statement since it can be true or false. It happens to be false. So its truth value is f. Now let us see the second sentence. A triangle has 3 sides. It is a statement as it is either true or false. We know that a triangle has 3 sides so this is a true statement. So we write the sentence a triangle has 3 sides is a statement it can be true or false and it happens to be true. So its truth value is t. The third sentence is what is your age? This is not a statement. It is a question. Questions are not considered as statements. So we write the sentence what is your age is not a statement as it is a question which cannot be true or false. This is the required answer. With this we complete our session. Hope you enjoyed the session.
