Triangle GUD , GU=DU and GD>DU. Which of the following is not true?​

A true-false statement is any sentence that is either true or false but not both. A negation of a statement has the opposite meaning of a truth value. A negations is written as ~p.

If we call the statement: cucumbers are green, p then:

p: cucumbers are green - this statement is true.

~p: cucumbers are not green - this statement is false.

If we join two statements we can form a compound statement or a conjunction. A conjunction could contain the two statements q and p:

p: cucumbers are green.

q: cucumbers are vegetables.

Conjunctions are noted:

p∧q

This is read - p and q. Cucumbers are green and vegetables.

A conjunction is true only if both statements that form the conjunction is true.

If we have two statements that are joined by "or" we have a disjunction.

Example:

p: Bill is travelling to Mexican q: Bill is travelling to Canada

p or q gives us that Bill is travelling to Mexico or Bill is travelling to Canada.

Disjunctions are noted:

p∨q

This is read - p or q.

A disjunction is true if at least one of the statements that form it is true.
