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.

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".

Disjoint sets are sets whose intersection, denoted by an inverted U), produces the null or the empty set. If a set is not disjoint, then it is called joint. [ex. M= {1,2,A} N = {4,5,B}. S intersection D is a null set, so M and N are disjoint sets.

Set relationships is what sets have in common. Here are examples: 1. Joint 2. Disjoint 3. Equivalent 4. Equal

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.

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

Joint sets:Joint sets are those which have common elements Disjoint sets : A pair of sets is said to be disjoint if their intersection is the empty set. That is to say, if they share no elements. All of the usual operations can be performed on disjoint sets, so long as the operation makes sense. (For example, taking the complement of one with respect to the other could pose problems.)

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

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

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

There is no such symbol for joint sets. Actually, there is a representation for joint sets. That is: The sets are joint if A ∩ B is not empty. The sets are disjoint if A ∩ B is empty.
