- If pthenq .
- p
- If q then not r .
- s or r .
Answer to Problem 31WE
From the given statements, it can be concluded that “ s is true”.
Explanation of Solution
Given information : It is given that four statements, if p then q ; p ; if q then not r ; s or rare all true and conclusions are to be drawn from them.
Formula used : Mathematical Logic
All the statements, if p then q ; p ; if q then not r ; s or r are true. So, from the second statement “ p is true”; from first statement “ p is true so q is true”; from third statement “ q is true so r is not true”; lastly from the fourth statement “ r is false but s is true”. The possible conclusion that can be drawn from all these are is that “ s is true”.
