Question 1
Rewrite the following statement in standard 'if-then' form:
"She won't come unless you invite her"
What is the equivalent conditional statement?
Step 1: Understand 'unless' statements
'P unless Q' means 'If not Q, then P'
In logical form: 'P unless Q' ≡ '¬Q → P'
Step 2: Identify components
Original: She won't come unless you invite her
p: She won't come, q: You invite her
Step 3: Convert to if-then form
'unless' tells us what happens if the condition is NOT met
Logical form: ¬q → p
Step 4: Write in English
Equivalent statement: If you do not invite her, then she won't come
'P unless Q' means 'If not Q, then P'
In logical form: 'P unless Q' ≡ '¬Q → P'
Step 2: Identify components
Original: She won't come unless you invite her
p: She won't come, q: You invite her
Step 3: Convert to if-then form
'unless' tells us what happens if the condition is NOT met
Logical form: ¬q → p
Step 4: Write in English
Equivalent statement: If you do not invite her, then she won't come
