Final answer:
To determine the marginal cumulative distribution functions of X and Y, we first need to compute the joint probability distribution. Once we have the joint probability distribution, we can calculate the cumulative distribution functions for each variable independently.
Step-by-step explanation:
Marginal cumulative distribution functions are not applicable in this context. To determine the marginal cumulative distribution functions of X and Y, we first need to compute the joint probability distribution. Once we have the joint probability distribution, we can calculate the cumulative distribution functions for each variable independently.
b) Compute the joint probability distribution first.
c) Calculate the cumulative distribution functions for each variable independently.
d) Both b and c
