Logic Disjunction

A disjunction is a compound statement formed by combining two simple sentences using the word “OR”. A disjunction is true when at least one of the simple sentences are true. The symbol for a disjunction is : All possible outcomes for a disjunction : Note: The only false disjunction is the last one, when both simple statements are false.

A disjunction is a compound statement formed by combining two simple sentences using the word “OR”. A disjunction is true when at least one of the simple sentences are true. Write each sentence symbolically and determine its truth value.
