A->b, C->~b, A /\ C->?

  1. Dec 21, 2003 #1
    Anyone know what the answer to this would be?
    A implies B
    C implies not B
    What happens when both A and C occur?

    I just asked my brother if he wanted to play basketball with me and my father. He said (as a joke) if I were going, he wouldn't go, but if my father were going, he would go. We were both going. So mathematically, which would he do?

    The statemetn [itex](A \Rightarrow B) \wedge (C \Rightarrow \neg B) \wedge (A \wedge C)[/itex] is identically false. IOW your brother lied. :smile:
