Discrete Structure Math

1. Use a truth table to explore the equivalence of the following two statements: $(p \land q) \rightarrow r$ and $(p \rightarrow r) \land (q \rightarrow r)$. Write a sentence explaining why they are or are not logically equivalent.

2. Write **negations** of the following statements:

a. Tom is healthy but not wealthy.

b. Juan is a computer science major, or he is not required to take Math 2110.

Expert Solution

Step 1

Let, T represents true

F represents false.

p	q	r	p $\land$ q	p $\to$ r	q $\to$ r	(p $\land$ q) $\to$ r	(p $\to$ r) $\land$ (q $\to$ r)
T	T	T	T	T	T	T	T
T	T	F	T	F	F	F	F
T	F	T	F	T	T	T	T
T	F	F	F	F	T	T	F
F	T	T	F	T	T	T	T
F	T	F	F	T	F	T	F
F	F	T	F	T	T	T	T
F	F	F	F	T	T	T	T

Since, the last two columns are not same

(p $\land$ q) $\to$ r and (p $\to$ r) $\land$ (q $\to$ r) are not logically equivalent.
