Question

Let s represent a false statement, let p represent a true statement, and let r represent a false statement. Find the truth value of the following statement. - [(s or -p) or r]

Answer 1

Answer: false

Work Shown:

s = false

p = true

r = false

-p = false, which is the opposite of statement p

s or -p = false or false = false

The result of an 'or' operation is false only when both parts are false; otherwise, it is true

(s or -p) or r = false or false = false

(s or -p) or r = false
