What is a mutually exclusive variable?
Mutually exclusive is a statistical term describing two or more events that cannot happen simultaneously. It is commonly used to describe a situation where the occurrence of one outcome supersedes the other.
How do you know if a variable is mutually exclusive?
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. and is not equal to zero.
What is an example of a mutually exclusive?
Mutually exclusive events are events that can not happen at the same time. Examples include: right and left hand turns, even and odd numbers on a die, winning and losing a game, or running and walking. Non-mutually exclusive events are events that can happen at the same time.

What is mutually exclusive in statistics example?
In statistics and probability theory, two events are mutually exclusive if they cannot occur at the same time. The simplest example of mutually exclusive events is a coin toss. A tossed coin outcome can be either head or tails, but both outcomes cannot occur simultaneously.
Is getting a red or a heart from a deck of 52 cards mutually exclusive?
Photo by Pixabay. The correct answer is B). Drawing a red card and drawing a club cannot occur at the same time, because all clubs are black; therefore, the outcomes drawing a red card and drawing a club are mutually exclusive.
How do you know if PA or B is mutually exclusive?
If two events A and B are mutually exclusive, the events are called disjoint events. The probability of two disjoint events A or B happening is: p(A or B) = p(A) + p(B).
What is the difference between independent and mutually exclusive?
The difference between mutually exclusive and independent events is: a mutually exclusive event can simply be defined as a situation when two events cannot occur at same time whereas independent event occurs when one event remains unaffected by the occurrence of the other event.
Are independent variables mutually exclusive?
If two events are mutually exclusive then they do not occur simultaneously, hence they are not independent. Yes, there is relationship between mutually exclusive events and independent events.
Is mutually exclusive dependent or independent?
Therefore, we see that a mutually exclusive pair of nontrivial events are also necessarily dependent events. This makes sense because if A and B are mutually exclusive, then if A occurs, then B cannot also occur; and vice versa.
