Only one is.
It is rolling 1 or 2.
If the die is rolled often enough, the event is a certainty - probability = 1. For a single roll, the probability is 1/2.
Before you roll the cube it is an even. Afterwards, it is an outcome.
For any event, the complementary event is all of the other possible outcomes. For an event (Rolling a number cube) " Rolling an odd number " The complementary event is " Rolling an even number "
Rolling a dice and getting an even number is an outcome. It is the result of rolling a dice.
When you roll two dice, a 7 may occur as (1,6),(2,5),(3,4),(4,3),(5,2),(6,1) There are 6 elements in the event space.
There are two elements in the event space. They are the rolls (6, 5) and (5, 6) .

An outcome is the result of a single trial. For example, if I roll a die, one outcome would be a six. An event is a collection of one or more outcomes. Using the example of rolling a die, an event might be rolling two sixes in a row. Thus this event is comprised of two outcomes - rolling and six and rolling another six.
If the die is rolled often enough, the event is a certainty - probability = 1. For a single roll, the probability is 1/2.
