Exercise 4 Page 441

There are four scenarios of a conditional statement.

See solution.

Practice makes perfect

A conditional statement can be expressed in if-then form.

if hypothesis then conclusion A hypothesis can either be true or false, and the same applies to a conclusion. For a conditional statement to be true though, the hypothesis and conclusion do not necessarily both have to be true — the only time a conditional statement is false is when a true hypothesis results in a false conclusion.

p	q	p→ q
T	T	T
T	F	F
F	T	T
F	F	T

We can see this illustrated in the truth table.
