推 itsweb : 語句沒有講到P欸？ 09/03 14:46
推 cutekid : Q xor R 09/03 20:24
→ yasfun : Neg(Q and R) = Not both 09/03 21:44
→ david830317 : 看來應該是答案錯了..一直想不到為什麼會扯到p 09/04 04:57
題目是英文的
題目如下
P: Sam has pizza last night
Q: Chris finish her homework
R: Pat watched the news this morning
Either Chris finish her homework or Pat watched the news this morning, but not
both.
我個人解讀是是Q或R其中一個
所以我自己答案是 Q OR R
但答案卻是 P OR Q and negative(p and q)
