African rhinos. Two species of rhinoceros native to Africa are black rhinos and white rhinos. The International Rhino Federation estimates that the African rhinoceros population consists of 5,055 white rhinos and 20,405 black rhinos.

Suppose one rhino is selected at random from the African rhino population and its species (black or white) is observed.

a. List the sample points for this experiment.

b. Assign probabilities to the sample points on the basis of the estimates made by the International Rhino Federation.
