Question 1
Consider the conditional statement:
"If p: You press the button, then q: The light turns on"
(p → q)
If p is True and q is False, what is the truth value of p → q?
Step 1: Understand the implication (→) operator
The implication p → q is False ONLY when p is True but q is False.
In all other cases, it is True.
Truth table for p → q:
p=T, q=T → Result=T
p=T, q=F → Result=F (the only False case)
p=F, q=T → Result=T
p=F, q=F → Result=T
Step 2: Apply the given values
p = True, q = False
Step 3: Evaluate p → q
Since p is True but q is False, the implication fails: p → q = False
The implication p → q is False ONLY when p is True but q is False.
In all other cases, it is True.
Truth table for p → q:
p=T, q=T → Result=T
p=T, q=F → Result=F (the only False case)
p=F, q=T → Result=T
p=F, q=F → Result=T
Step 2: Apply the given values
p = True, q = False
Step 3: Evaluate p → q
Since p is True but q is False, the implication fails: p → q = False
