P(A l B)  =       .24                                                  P( B l A)  = .24

                _____________  =   4/7  = .57                                ____  =   3/5  = .60

                       .42                                                                      .40

 

P(A)  = .40

 

P(B) = .42

 

 

Not independent because   

P(A l B)  not equal P(A)     and P(B l A)  not equal to B
