Question

Let S={x,y,z} be a sample space of an experiment with outcomes x,y,and z. List all the events of the experiment.

Answer 1

not too sure what that means, i think it means list all the possible permutations .. but it doesnt really say that there are multiple draws or somesuch

Answer 2

the power set maybe?

Answer 3

{}
{x}, {y}, {z}
{x,y}, {x,z}, {y,z}
{x,y,z}

so 8 events

Answer 4

an event is: anything you want to know a probability for

so the probability of: none, x, y, x, xy, xz, yz, xyz

sounds right ....
