Ans :
The syntax of propositional logic allows two types of sentences to represent
knowledge. The two types are as follows:
1- Atomic Propositions
These are simplest propositions containing a single proposition symbol and are
either true or false. Some of the examples of atomic propositions are as follows:
- “Venus is the closest planet to the Sun in the solar system” is an atomic
preposition since it is a false fact. - “7 – 3 = 4” is an atomic preposition as it is a true fact.
2- Compound Propositions
They are formed by a collection of atomic propositions joined with logical
connectives or logical operators. Some of the examples of compound
propositions are as follows:
- The Sun is very bright today and its very hot outside.
- Diana studies in class 8th and her school is in Karol Bagh.
