If two events A and B are mutually exclusive, the special rule of addition states that the probability of one or the other event's occurring equals the sum of their probabilities. This rule is expressed in the following formula:

If two events are mutually exclusive what is the probability that one or the other occurs?
Add the probabilities of the two events. If they're not mutually exclusive, then you need to subtract the probability that they both occur together.
Are the events polka dot and plaid mutually exclusive?
The answer will depend on the trial - and possibly the fashion sense!
What are two events that cannot occur at the same time called?
Two events that cannot occur at the same time are called mutually exclusive.
When events are mutually exclusive and exhaustive then the sum of the individual probabilities of each event in the set must equal 1.00?
Yes.
Are events and its complement mutually exclusive?
Yes, they cannot happen at the same time. If you flip a coin heads and tails can not come up at the same time.
The Special Rule of Addition is used to combine?
Mutually exclusive events.
Is it true the special rule of addition is the events must be mutually exclusive?
yes
What is the definition of mutually exclusive events?
The definition of mutually exclusive events is that the events can't occur at the same time. For example, you can't flip a coin and get a head and a tail; they are mutually exclusive events.
What is potentially inclusive events?
It is the opposite of mutually exclusive. Potentially inclusive are events that can happen at the same time, as mutually exclusive events can't.
What function do you use to calculate the probabilities of compound events?
To calculate the probabilities of compound events, you can use the multiplication rule or the addition rule, depending on whether the events are independent or mutually exclusive. The multiplication rule is used when the events are independent, and you multiply the probabilities of the individual events. The addition rule is used when the events are mutually exclusive, and you add the probabilities of the individual events.
If two events are mutually exclusive then they must be dependent?
No, if two events are mutually exclusive, they cannot both occur. If one occurs, it means the second can not occur.
Can two mutually exclusive events occur at the same time?
No because the term mutually exclusive implies the the trials that could result in these events are sequenced in time.
What is True about mutually exclusive events?
At most one of the events can occur.
How determine probablity for mutually exclusive events?
Mutually exclusive events are considered two events that cannot coexist with one another, in other words, if the first event is happening the second just cannot. Determining the probability for mutually exclusive events can be done by using the formula P ( A and B ) = 0.
Are dependent events always mutually exclusive?
Yes.
Are complementary events also mutually exclusive events?
Yes, they are. Mutually exclusive events cannot occur together. Complementary events cannot occur together either because an event and its complement are the negative of each other.
In maths What is Mutually exclusive probability?
Mutually exclusive means they are independent of one another. So, the two events are independent of one another.
