The even numbers that can be rolled on a single die are 2,4, and 6 so the number of elements in the event space is 3. X={2,4,6}.
When rolling two dice, the event space for obtaining a sum of 6 consists of the following combinations: (1, 5), (2, 4), (3, 3), (4, 2), and (5, 1). There are 5 possible outcomes that result in a sum of 6. Therefore, the number of elements in the event space is 5.
Three.
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.
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.
