Q. 2 The logically equivalent statement of p -->q is(c) 4(d) 1 |
|
Answer» p implies q= p⟹q≡¬[p∧¬q]p⟹q≡¬[p∧¬q] for example : consider a statement P:If it is raining then it is cloudy. A common misperception is that this means that cloudiness causes rain, or that rain causes cloudiness. Neither is the case. [Edit: It just means that,at a given instant in time, it is not both raining and not cloudy. There is no suggestion of the passage of time or an historical record.] Raining⟹Cloudy≡¬[Raining∧¬Cloudy] |
