Premise: Some Xs are Ys
Premise: All Ys are Z's
Conclusion: SOme Ws and Z's
this is how i drew
is this correct
The missing premise is All W's are X?
because the right answer is all Xs are Ws?
You have it reversed in part of your text. Adding in X --> W would lock it up.
X Y --> Z
Valid conclusion: W Z
thankkkk you Jeffort! makes so much sense.
but please tell me i am reasoning right in this one:
No A's are B's . Some Bs are C.
A<--|--> Bsome C
does not it give me: Asomenot C?
I don't know... this problem came to me in my dream ...shows how obsessed i am with LSAT
