A fishpond contains 20 orange fish and 10 green fish. A sample of five fish is taken (withoutreplacement) from the pond. Let X denote the number of orange fish in the sample.(i) State the type of distribution of X, and write down its mass function.(ii) Hence find P(X = 2).(iii) If the sample contains at least four orange fish, how likely is it to contain only orangefish?

Question
A fishpond contains 20 orange fish and 10 green fish. A sample of five fish is taken (without
replacement) from the pond. Let X denote the number of orange fish in the sample.
(i) State the type of distribution of X, and write down its mass
(ii) Hence find P(X = 2).
(iii) If the sample contains at least four orange fish, how likely is it to contain only orange
fish?
