The event A = (1,4) and has occurred when the dice is tossed and it shows a 1 or 4. It could also be defined as Event A=numbers not including 2,3,5 or 6Event B has occurred when the dice shows a 6 or B could also =numbers other than 6; C = ‘1,2 or 3’is rolled; and D occurs when the dice throw results in 2,3 or 5. As noted in Event A, each event can also be defined by what is not wanted.

Then I started second guessing myself and feel like I don't get it at all. The question I'm trying to answer also asks about which event forms a "partition" of the sample space...not sure what this means and can't find a definition. I look forward to any suggestions.

Thanks
