Question text Fill in the missing parts for the proof of validity of the following argument: It is not sunny this afternoon and it is colder than yesterday. • We will go swimming only if it is sunny. • If we do not go swimming, then we will go island hopping. • If we go island hopping, then we will be home by sunset. • Therefore, we will be home by sunset. ● Let the following symbols represent the corresponding statements: s - It is sunny this afternoon. c - It is colder than yesterday. w - We will go swimming today. i - We will go island hopping. h- We will be home by sunset. Thus, in symbolic form, we have ~SAC ws ~wi i → h :. h A proof of validity: step statement reason
