离散数学 (p∧q)→ r
Let p be the proposition “You have the flu", q be the proposition ”You miss the x0cfinal
examination" and r be the proposition“You pass the course". Express the following as an English
sentence: (p→~r)∨(q→~r)
答案就是 if p,then ~r or if q ,then~r.
但是上面那个式子 等于 (p∧q)→ ~r 对不对
那如果 写 if p and q,then ~r 对不对
