                                              Kejadian Majemuk




                                              Kejadian Bersyarat







            Erin thinks of a number from 1 to 10


            (say 8) and asks Peter to guess what



            it is. Find the probability that Peter                                                                                                                                ?


            makes a correct guess on his first try                                                                    8


            if Erin first tells Peter that the number


            is greater than 7.
