If the random variables X and y are independent of each other and obey the uniform distribution on the interval (0,1), then the following random variables obey the uniform distribution A.x & # 178; b.x + y, C. (x, y) d.x-y, please give me a process,

If the random variables X and y are independent of each other and obey the uniform distribution on the interval (0,1), then the following random variables obey the uniform distribution A.x & # 178; b.x + y, C. (x, y) d.x-y, please give me a process,

C
x. Y is independent, so the squares of (x, y) in their (0,1) intervals on the XY plane are uniformly distributed
A is obviously wrong. You can take any value from 0 to 1 to disprove it
The distribution of B and D is oblique two straight lines in XY two-dimensional graph
