Two species of rhinoceros native to Africa are black rhinos and white rhinos. In 1998, the International Rhino Federation estimated that the African rhinoceros population consisted of 2,600 white rhinos and 7,400 black rhinos. Suppose two African rhinos are selected at random and their species observed. (a) Explain how to use random digits to simulate the random selection of a rhino. Then use the table of random digits at the start of line 102 to simulate the selection of two rhinos. (b) Repeat the previous step 20 times, continuing on line 103 when necessary, writing down all the digits you obtain, and estimate the probability of selecting two rhinos of different colors.
