Hi guys,
I believe there are one or two errors in the wording of this problem and I need to make sure I know what they are before I actually do this problem. The problem reads:
Suppose that is a random variable for Let
(a) Find
(b) Find
Would it make more sense for the problem to read "Suppose that (instead of )is a random variable..." and instead of ?
Also, for (a) and (b), did the author mean "Find " and "Find " instead of and respectively?
Thanks for any help!
James
Thanks for your replies.
The question is worded exactly as in the original post, except for a small typo on my part it should have been:
(b) and not
If the wording of the problem is correct, could you please help me understand the question. Since our pdf is for the random variable , woudn't we need some relationship between and , and then from to (which we have since ) in order to do this?
Best,
James
OK, looking at it closer I see what you mean. It would make sense to be asked to find the pdf for Y = R^3 since the question does not define the random variable X anywhere.
I suggest you ask whoever set the question. I recant my earlier opinion and would suggest there is a typo in the definition of Y.
