25% of Flapper fish have red spots, the rest have blue spots. A fisherman nets 10 flapper fish. What are the probabilities that:

(i) exactly 8 have blue spots ?

(ii) atleast 8 have blue spots ?

A large number of samples, each of 100 flapper fish are taken.

(iii) What is the mean and standard deviation of the number of red spotted fish per sample ?

(iv) What is the probability of a sample of 100 flapper fish containing over 30 with red spots ?
