PS: I know how to do the truth table, but my question is that how do you consider if it's true when they use the symbol "or"? When you do this question, can you please try to explain the "q or r" part detailed? Thank you!

Complete the truth table shown below. Hint: you may find it helpful to do this on paper first, and add columns for the intermediate expressions and .

p	q	r
False	False	False	[ Select ] ["True", "False"]
False	False	True	[ Select ] ["True", "False"]
False	True	False	[ Select ] ["False", "True"]
False	True	True	[ Select ] ["False", "True"]
True	False	False	[ Select ] ["True", "False"]
True	False	True	[ Select ] ["False", "True"]
True	True	False	[ Select ] ["True", "False"]
True	True	True	[ Select ] ["True", "False"]
