b. Are the events being female and preferring the coastline independent events?
Let F = being female and let C = preferring the coastline.
(a) Find P(F AND C).
(b) Find P(F)P(C).
Are these two numbers the same? If they are, then F and C are independent. If they are not, then F and C are not independent.
