True or False: Whether Diamond selects a phone case with a pop socket is independent of her sister borrowing one of her pop socket phone cases. True or False: Whether Diamond selects a phone case with a pop socket is independent of her sister borrowing one of her pop socket phone cases. True False call the probability in Part B a conditional probability because we calculated Diamond's probability of selecting a case with a pop socket conditional on the fact that her sister had taken one of her cases. We write this as: P(Diamond selects case with pop socket GIVEN her sister took one case with pop socket) The probability of Diamond selecting a phone case with a pop socket is impacted by her sister borrowing one of the phone cases. In this example, one event occurring impacts the probability of another event occurring. However, this is not always the case. Sometimes, there are pairs of events for which one event has no effect on the probability of another event occurring. When this is the case, we say the events are independent. More formally: Events A and B are independent if P(A GIVEN B) = P(A)
