Please answer and explain why each is true or false thoroughly. Thank you!

True or False? If X & Y are jointly Gaussian, then each of them is Gaussian. If X & Y are Gaussian, they may not be jointly Gaussian. If X & Y are independent & Gaussian, they are jointly Gaussian. If X & Y are Gaussian, their sum may not be Gaussian. If X & Y are independent & Gaussian, their sum is Gaussian. If X & Y are uncorrelated & Gaussian, they may not be independent. If X & Y are uncorrelated & jointly Gaussian, they are independent.
