Question 1138258: a pollster plans to call adults. She has a list of names and numbers of 100 adults, consisting of 60 males and 40 females. she will make random selections and will not call the same person more than once.
a. consider the event of getting a male on first selection and getting a female on the second selection. are these independent or dependent events?
b. what is the probability of getting a male on the first selection and getting a female on the second selection?

The first is (60/100) and the second given the first is (40/99). The joint probability is 0.242
These are not independent, because once a male is selected, there is a slight but definite change in the probability of a female's being selected.
