A researcher randomly selects one of the birds in the laboratory for study.
a. What is the probability that the researcher selects a bird with a short beak? What is the probability
that the researcher selects a bird with white feathers?
b. Given that the researcher selected a blue bird what is the probability that it has a short beak?
omocamGiven that a researcher did not select a blue bird, what is the probability that it has a long beak?
B mcHow does this conditional probability compare to the unconditional probability that the bird has a
long beak? What does this tell you about independence?
