If the die is rolled often enough, the event is a certainty - probability = 1. For a single roll, the probability is 1/2.

The probability that, when rolling three dice none will come up odd is broken down by the probability that on odd roll will occur as an independent event. Rolling the first die has a probability of 3/6 that it will be odd. Rolling the second has the probability of 3/6 that it will be odd. Rolling the third has a probability of 3/6 will be odd. Rolling three and coming up with odd is really the probability that no odd numbers occurred, so therefore an even number DID happen (3/6), and an even number DID happen (3/6), and an even number DID happen (3/6). That's really just 1 - (3/6^3) or simplified 1 - (1/2^3). So therefore the probability that an odd number occurred in 3 die rolls is about 87.5%.

Yes, it can be

If the probability of a event is zero, then the event cannot occur. Therefore, if the probability of an even number is zero, then the probability of an odd number is one.

Odds of rolling seven once (2 dice) is 1:6, twice in a row, odds are 1:36. The reason is- the first die can be any number, but the second die must be a particular number. For example, if the first die is 6, then the second die has to be 1 to make 7. When an event occurs twice, and the two events are unrelated, then you can multiply the odds together= 1/6 * 1/6 = 1/36.

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) .

Three.

Only one is.

It is rolling 1 or 2.

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.

Before you roll the cube it is an even. Afterwards, it is an outcome.

If the die is rolled often enough, the event is a certainty - probability = 1. For a single roll, the probability is 1/2.
