     A) .1875           B) .2255              C) .2500             D) .3205

  Solution:
                    Probability is the numerical measure of the chance of an outcome or event occurring.
                    When all outcomes are equally likely occur, the probability of the occurrence of a given
                    outcome can be found using the following formula:

                                               probability = number of favorable outcomes
                                                                    number of possible outcomes        

                    number of favorable outcomes: 24 (Germany)

                    number of possible outcomes:  50 + 30 + 24 + 16 + 8 =  128    

                                               probability =  24ddd
                                                                   128

                                               probability =  0.1875

 

 Answer:  A) .1875
