Question

the dual of ~(pvq)^(pv(p^~r)) is​

Answer 1

Step-by-step explanation:

The dual of a proposition that contains 

only the logical operators ∨,∧ can be obtained  

by replacing each ∨ by ∧ and each ∧ by ∨

So given statement 

=p∧[q∧(p∨q)∧r]

⇒ The dual will be =p∨[q∨(p∧q)∨r] Ans 

→ Required Answer c.
