Question
Mathematics Question on mathematical reasoning
Let p and q be two statements Then ∼(p∧(p⇒∼q)) is equivalent to
A
p∨(p∧q)
B
(∼p)∨q
C
p∨(p∧(∼q))
D
p∨((∼p)∧q)
Answer
(∼p)∨q
Explanation
Solution
The correct answer is (B) : (∼p)∨q
∼(p∧(p→∼q))
≡∼p∨∼(∼p∨∼q)
≡∼p∨(p∧q)
≡(∼p∨p)∧(∼p∨q)
≡t∧(∼p∨q)
≡∼p∨q
