Section 3 From a group consisting of 2 Douglas-fir, 3 hemlock and 1 balsam fir seedlings, 3 are to be randomly selected. Let X denote the number of hemlock seedlings, and Y the number of Douglas-fir seedlings.Part 1: What is the probability of choosing zero Douglas-fir, 2 hemlock, and the remainder balsam fir seedlings? 0 0.3 0 0.15 0.05Part 2: The table below shows the joint probability distribution of X and Y. Fill in the missing probabilities. Hemlock (X) Douglas- 0 1 fir (Y) 2 3 0 NA NA 0.15 0.05 1 NA .3 .3 NA 2 0.05 0.15 NA NA Hint: the probability value ranges from 0 to 1. Some combinations are not possible and for those cases, you can enter either of the following: NAPart 5: True or False: X and Y are independent. Hint: if X and Y are independent then select "True" otherwise select "False" O True
