Identify the complex sentence of the following statement:
Sally has a basketball and she sells it to her friend Bob.
First-order logic statements can be described in complex sentences by using logic symbols.
Recall the following logic symbols.
means "not"
means "implies"
means "or"
means "and"
means "equivalent"
For this particular problem the starting sentence is,
"Sally has a basketball and she sells it to her friend Bob."
First, identify the first-order statements and write them in symbolic form. This particular sentence has two first-order statements.
Statement 1: Sally has a basketball
Statement 2: Sally sells her basketball to her friend Bob.
To combine these statements into one complex sentence, it needs to be understood that once Sally sells her basketball she no longer has it therefore, the statement becomes:
