Let S be the sample space of an experiment Y be a rv defined

Let S be the sample space of an experiment, Y be a r.v. defined for the experiment, and W be the support of Y.

The domain of a function is the set of values no which the function is defined.

A) Which of the following is the domain of the density function for Y

i. S
ii. W
iii the set of real numbers

*pleae include your reasoning in your answer* Thanks

Answer is W.

W is giving the values that y can take as W is the support of Y.

Hence W is the domain for the density funciton of Y.
