Predicate logic uses predicates to describe properties or relations among objects. Predicates are represented by propositional functions like P(x) which denotes "x is a student". Predicates are quantified using quantifiers like the existential quantifier ∃ and universal quantifier ∀. The existential quantifier denotes there exists an object with a certain property, while the universal quantifier denotes a property is true for all objects. When quantified propositions are negated, an existentially quantified proposition becomes universally quantified, and vice versa, according to De Morgan's laws.

Random variables and probability distributions Random Va.docx
1. A random variable is a function that associates a numerical value with each outcome of an experiment. Random variables can be discrete, taking countable values, or continuous, taking any real values.
2. Probability distributions describe the behavior of random variables through properties like expected value and variance. The expected value indicates the average or central value, while variance measures how spread out the values are around the average.
3. Common probability distributions include the binomial, describing count outcomes of independent yes/no trials, the normal describing measurements that tend to cluster, and the Poisson describing rare events that occur independently at a constant rate.
Lecture 2 predicates quantifiers and rules of inference
1) Predicates become propositions when variables are quantified by assigning values or using quantifiers. Quantifiers like ∀ and ∃ are used to make statements true or false for all or some values.
2) ∀ (universal quantifier) means "for all" and makes a statement true for all values of a variable. ∃ (existential quantifier) means "there exists" and makes a statement true if it is true for at least one value.
3) Predicates with unbound variables are neither true nor false. Binding variables by assigning values or using quantifiers turns predicates into propositions that can be evaluated as true or false.

1. The document discusses random axioms and probabilistic proofs in Peano arithmetic. It describes a proof strategy where one could randomly select an integer n that satisfies some formula φ and add it as a new axiom.
2. While this intuition of probabilistic proofs makes sense, it is not really useful since any statement provable with sufficiently high probability is already provable in PA. However, probabilistic proofs can be exponentially more concise than deterministic proofs.
3. The document also discusses Kolmogorov complexity and how statements about it relate to the provability of PA. It can be shown that if C(x) is less than some value, PA will prove it, but PA will never prove a
Chapter 2 - Speaking Mathematically.pdf
This document introduces some key concepts in set theory and mathematical language. It defines what a set is, and introduces ways to represent sets using roster notation. It discusses well-defined sets and the symbols to denote whether an element is or is not part of a set. Examples are provided to illustrate definitions of natural numbers, integers, rational numbers, and real numbers. The document also covers universal and existential statements, and how to rewrite them using variables.
Chapter 01 - p2.pdf
This document provides an overview of predicate logic, including:
- The basic components of predicate logic like variables, predicates, quantifiers, and propositional functions
- Explanations of the universal and existential quantifiers
- How to negate quantified expressions using De Morgan's laws
- Examples of translating statements between English and predicate logic
Per3 logika&pembuktian
This document provides an overview of logic and proofs. It begins by defining logic as the study of correct reasoning, and discusses how logic is used in mathematics and computer science. Some key concepts introduced include:
- Propositions and truth values
- Logical connectives like AND, OR, NOT
- Truth tables for evaluating compound propositions
- Quantifiers like "for all" and "there exists"
- Propositional functions and their domains
- Types of proofs like direct proof, proof by contradiction, and mathematical induction
The document concludes by covering resolution proofs and the strong form of mathematical induction, which involves verifying a basis step and proving the induction step. Overall, it serves as an introduction to
Probability and Randomness
This document covers key concepts in probability, including sample spaces, events, rules of probability such as addition and multiplication, and conditional probability. It defines probability as the proportion of times an outcome occurs in a long series of repetitions. It introduces terminology like the sample space, events, and rules for calculating probabilities of individual events and combined events, depending on whether they are disjoint, independent, or conditional. Several examples demonstrate how to apply the rules of probability, addition, multiplication, and conditional probability to calculate probabilities in finite sample spaces.
Propositional logic
This document provides an overview of propositional logic, including:
- Propositions are statements that can be true or false. Compound propositions combine simpler statements with logical connectives like "and" and "or".
- Truth tables show the truth values of compound propositions based on the truth values of their variables.
- Common logical connectives include conjunction, disjunction, negation, implication, and equivalence.
- Tautologies and contradictions are types of statements that are always true or false regardless of variable values.
- Quantifiers like "for all" and "there exists" can be used to define propositional functions on a domain.
- Valid arguments are those where the conclusion is necessarily true
First order logic or Predicate logic.pptx
First order logic uses predicates, terms, and quantifiers to form atomic and complex sentences. Atomic sentences are formed from a predicate symbol followed by terms in parentheses. Complex sentences combine atomic sentences using logical connectives. Quantifiers like ∀ and ∃ are used to quantify variables in predicates. The unification algorithm tries to unify two first-order logic expressions by recursively matching and substituting their components, returning a substitution set if fully matched or FAILURE if a mismatch is found at any point.

Implication And Biconditional
This document discusses logical conditionals. It defines implication (conditional) as two statements connected by "if p, then q" and represented by p → q. Implication is true except when the antecedent (p) is true and consequent (q) is false. Bi-conditional is defined as two statements connected by "p if and only if q" and represented by p ↔ q. It is true except when one statement is true and the other false. Examples of implication and bi-conditional are provided along with their truth tables.

Quantifier And their Negation
- 2. We have to learn, Quantifier Negation Of Quantifier
- 3. Quantifier The use of phrases like ‘ there exists ’ and ‘ for all ’ or ‘ for every’ is abundant in mathematics . These phrases are called as Quantifiers . Example: 1. For every a set A , A 2. There exists a real number x such that 2 0x . .
- 4. Symbol o ‘ There exists ’ is represented by o ‘ For all ’or ‘For every ’is represented by is called an Existential Quantifier. is called a Universal Quantifier.
- 5. Negation of Quantifier The negation of Existential quantifier will be Universal quantifier and vice versa . ~(there exists p) = for all ( ~p ) or ~(for all p) = there exists ( ~p ) or ~ ( ) (~ )p p ~ ( ) (~ )p p
- 6. Examples Find the negation of given statement: 1. For every , 0 0x R x x 2. There exists x R such that 2 1x Answer: 1. There exists x R such that 0 0x x 2. For every x R , 2 1x
