A study of birds in California found 110 hummingbirds, 50 robins, 30 warblers, and 10 mockingbirds. Show work. Please focus more on part d. a) If a bird is randomly chosen from this study, what is the probability that it will be a hummingbird? b) If a bird is randomly chosen from this study, what is the probability that it will be a robin or mockingbird? c) If two birds are randomly chosen from this study, what is the probability that one will be a robin and the other will be mockingbird?

d) If an bird is randomly chosen from the population and then returned to the population (total number of birds is the same for all trials), what is the probability that we will select a hummingbird, then a mockingbird, and then a warbler?
