An example of an event would be X>3, which is {4, 5, 6}. This is not an individual outcome (which I think is what they mean by "single event"), but a subset of outcomes whose probability one might ask for (e.g. making a bet on).Consider the rolling fair a die
i). write down the sample space ,all single events , all possible events
(i). Ω = {1,2,3,4,5,6} all single events = 6 {1} {2} {3} {4} {5} {6}
what is mean by possible events?
ø {1} {2} {3} {4} {5} {6}
is correct
Thanks for you.[/MATH][/MATH]
Without any indication to the contrary, potentially every subset of [MATH]\Omega[/MATH] may be considered an Event. Unfortunately there are [MATH]2^6=64[/MATH] such subsets!
Without any indication to the contrary, I suppose you could say that potentially, the set of Events is the powerset of [MATH]\Omega[/MATH], (the set of all subsets), which is denoted [MATH]2^\Omega[/MATH]. In any case the set of Events is a subset of the powerset.

So, as @lex said, you need to list all subsets of your sample space: not just the 7 you listed (the first of which has probability 0, so they may not want you to include this as a possible event), but for example {1, 2}, {2, 5, 6}, and so on. They may be asking you to write that out just this once, to show you that you don't want to have to do that all the time!
