a b and c are independent events?
537186
Let A and B be independent events, and let A and C be independent events. ... According to the definition of independent events, A and B∪C are independent if and only if P(A∩(B∪C))=P(A)P(B∪C).

In the case of two mutually exclusive events A and B, each of which has non-zero probability, we have that P(A)P(B)≠0, but P(A∩B)=0, so the events cannot be independent.

Definition: Two events, A and B, are independent if the fact that A occurs does not affect the probability of B occurring. Some other examples of independent events are: Landing on heads after tossing a coin AND rolling a 5 on a single 6-sided die. Choosing a marble from a jar AND landing on heads after tossing a coin.

Formula for the probability of A and B (independent events): p(A and B) = p(A) * p(B). If the probability of one event doesn't affect the other, you have an independent event.

If events A and B are independent, and the probability that event A occurs is 83%, what must be true? The probability that event A occurs, given that event B occurs, is 83%.

The probability of the events are said to be disjoint, meaning that they cannot interact, are strictly independent. If the probability of event A is mutually exclusive with event B, then the joint probability of event A and event B is zero.

A and B are mutually exclusive events if they cannot occur at the same time. This means that A and B do not share any outcomes and P(A AND B) = 0.

If events are disjoint then they must be not independent, i.e. they must be dependent events. Why is that? Recall: If A and B are disjoint then they cannot happen together. In other words, A and B being disjoint events implies that if event A occurs then B does not occur and vice versa.

A and B are mutually exclusive events if they cannot occur at the same time. This means that A and B do not share any outcomes and P(A AND B) ... Therefore, A and C are mutually exclusive.

An independent event is an event in which the outcome isn't affected by another event. A dependent event is affected by the outcome of a second event.

Two disjoint events can never be independent, except in the case that one of the events is null. ... Events are considered disjoint if they never occur at the same time. For example, being a freshman and being a sophomore would be considered disjoint events. Independent events are unrelated events.

Mutually exclusive events cannot happen at the same time. For example: when tossing a coin, the result can either be heads or tails but cannot be both. Events are independent if the occurrence of one event does not influence (and is not influenced by) the occurrence of the other(s).

Note that disjoint events and independent events are different. Events are considered disjoint if they never occur at the same time; these are also known as mutually exclusive events. Events are considered independent if they are unrelated. Two events that do not occur at the same time.

['If A and B are dependent events, then the probability of A happening AND the probability of B happening, given A, is P(A) × P(B after A).', 'P(A and B) = P(A) × P(B after A)', 'then P(A and B) = P(A) × P(B | A)', 'Example:', 'Example:', 'Solution:']

A and B are independent if and only if P(A∩B)=P(A)P(B). In general, one cannot say whether two events are independent or not without knowing the actual probability distribution (though there are some exceptions).
1125499
A and B are two events. If A and B are independent, then the probability that events A and B both occur is: p(A and B) = p(A) x p(B).
