Question
a)
Define the appropriate variables and write the following statement in symbolic form.
"If it's not because of heavy rain, then the rider would not be delayed, and the customer will
give a high rating to the delivery service"
b)
Given,
a: 4 < 8, b: 8<5, c: 4<5
Represent the following compound propositions symbolically and determine whether each
compound proposition is true or false.
If (4<5 or (8 < 5)) then, 4<8
It is not the case that (4 <8 and 4<5)
1.
11.
Use truth table to verify the following logical equivalence.
(p → q) v (p → r) = p → (q v r)
d)
Given the logical equivalence,
pvq-→r = (p→r)^(q>r)
Write the statement that is logically equivalence to the following statement
If y> 3 or y<-3, then y >9.
