According to some literature you found, 60% of the population is green while 40% of the population is brown. In addition, you should find a relatively equal proportion of male and female pipefish. Prior to your sampling, your interested in predicting the following probabilities:

a) P(male U green) :

b) P(brown | female) :

c) If you caught 50 pipefish, how many would you expect to be brown males?
