# lecture 11: quantifiers in discrete mathematics in urdu, universal quantifier existential quantifier

In this lecture, you will learn what quantifier in discrete mathematics ?
what are types of quantifiers in discrete mathematics – universal and existential quantifiers with example.

This discrete mathematics tutorial is actually a second part of lecture 10 -predicates and quantifiers discrete math in urdu and hindi language in which I had explained what is predicate and what is propositional logix p(x). However, today I will explain what is quantifier and how quantifiers in discrete mathematics are used to create proposition from predicate without assigning value to variable.

WRITTEN EXPLANATION OF TOPICS COVERED IN THIS DM VIDEO:

1. what is quantifier in discrete mathematics?
A quantifier is an operator used to create a proposition from a propositional function. An other way, if we do not assign values to p(x)

2. what is quanitfier meaning in urdu ?
Miqdaar batane waali cheez

3. what are types of quantifiers in discrete math ?
There are two types of quantifiers in discrete mathematics – universal quantifier and existential quantifier ;

4. what is universal quantifier
P(x) is true For all values of x in the universe of discourse

5. what is existential quantifier
There exists a value of x in the universe of discourse such that P(x) is true

6. what is difference between universal and existential quantifiers with example
What is the truth value of for all x P(x), where P(x) is the statement “x2 less than 10” and the universe of discourse consists of positive integers not exceeding 4?
False
but in case of existential quantifier let’s see;
What is the truth value of existential x P(x), where P(x) is the statement “x2 less than 10” and the universe of discourse consists of positive integers not exceeding 4?
True
