2) independent because P(B|A)≠P(A)
3) dependent because P(A|B)≠P(B)
4) independent because P(A and B)≠P(B|A)*P(A)
5) dependent because P(A and B)=P(A)+P(B)
6) independent because P(A and B)=P(A)*P(B)
7) dependent because P(B|A)=P(A)
8) independent because P(A|B)=P(B)
9) dependent because P(A and B)=P(B|A)*P(A)
10) independent because P(A and B)≠P(A)+P(B)
11) dependent because P(A and B)≠P(A)*P(B)
12) independent because P(A and B)=0
