Two events are disjoint if they cannot occur together. In set terms, their intersection is a null set.

Multiply the possible outcomes of the events in the disjoint events

In probability theory, disjoint events are two (or more) events where more than one cannot occur in the same trial. It is possible that none of them occur in a particular trial.

I asked this question so someone please help me in this question?

Yes,Because not all disjoint no equivalent other have disjoint and equivalent

Not necessarily. For a counterexample, A and C could be the same set.

A disjoint event is an event that can not happen at the same time

Two sets are said to be "disjoint" if they have no common element - their intersection is the empty set. As far as I know, "joint" is NOT used in the sense of the opposite of disjoint, i.e., "not disjoint".

If two events are disjoint, they cannot occur at the same time. For example, if you flip a coin, you cannot get heads AND tails. Since A and B are disjoint, P(A and B) = 0 If A and B were independent, then P(A and B) = 0.4*0.5=0.2. For example, the chances you throw a dice and it lands on 1 AND the chances you flip a coin and it land on heads. These events are independent...the outcome of one event does not affect the outcome of the other.

If they're disjoint events: P(A and B) = P(A) + P(B) Generally: P(A and B) = P(A) + P(B) - P(A|B)

If they are disjoint faces, then 6*4 = 24 vertices.If they are disjoint faces, then 6*4 = 24 vertices.If they are disjoint faces, then 6*4 = 24 vertices.If they are disjoint faces, then 6*4 = 24 vertices.

Two sets are considered disjoint if they have no elements in common.

Sets are not disjants, they are disjoint. And two sets are disjoint if they have nothing in common. For example, the set {1,3,5} has nothing in common with the set {2,4,6}. So they are disjoint.

He gets exactly one Head and he gets exactly two heads.

they dont share common elements...thats why their disjoint..g??

When two sets do not have any elements common between them,they are said to be disjoint.

ExplanationFormally, two sets A and B are disjoint if their intersection is the empty set, i.e. if This definition extends to any collection of sets. A collection of sets is pairwise disjoint or mutually disjoint if, given any two sets in the collection, those two sets are disjoint.Formally, let I be an index set, and for each i in I, let Ai be a set. Then the family of sets {Ai : i ∈ I} is pairwise disjoint if for any i and j in I with i ≠ j,For example, the collection of sets { {1}, {2}, {3}, ... } is pairwise disjoint. If {Ai} is a pairwise disjoint collection (containing at least two sets), then clearly its intersection is empty:However, the converse is not true: the intersection of the collection {{1, 2}, {2, 3}, {3, 1}} is empty, but the collection is not pairwise disjoint. In fact, there are no two disjoint sets in this collection.A partition of a set X is any collection of non-empty subsets {Ai : i ∈ I} of X such that {Ai} are pairwise disjoint andSets that are not the same.

getting at least two heads and getting at least two tails

No, only if both sets are empty. The intersection of disjoint sets is always empty.

There are 16 simple events in the sample space of four puppies.

The difference between joint sets and disjoint sets is the number of elements in common. A disjoint set, in math, does not any elements in common. A joint set must have at least one number in common.

joint disjoint point

Joint sets are sets with common element/s. Disjoint sets are sets without any common element/s.

Because they are disjoint, (ie. they contain none of the same elements) their intersection (what they both share in common) is the empty or null set.

Her answer to the question seemed disjointed.
