A group of people were asked what form of exercise they participate in. They were asked whether they walk, run, both walk and run, or neither walk nor run.
The table shows the probabilities of the results.
.
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
