Not necessarily. For a counterexample, A and C could be the same set.
First you must understand the term of disjoint sets. This is when both sets have no elements in common.Ex: A={2,3,4} B={1,5,9}. Since A has no similar numbers in B and likewise, they are disjoint.A is a partition of a finite or infinite collection of nonempty sets G= {A,B,C,D...},Iff:1) A is in the union of all {A,B,C,D...}2) The sets A,B,C,D...are all mutually disjoint (no overlapping of elements)So in other words, A=/B=/C=/D=/... ---(=/ is 'does not equal')---i.e. (A intersect B) = {} ---- ({} is an empty set)---
Yes,Because not all disjoint no equivalent other have disjoint and equivalent
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.)
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.
A=B , A-B=B-B , A-B =0 B=C , B-B=C-B, 0=C-B So A-B=0 but also C-B=0 A-B=C-B ...add +b ...A-B+B=C-B+B , A=C

The symbol for disjoint sets is typically represented by the symbol "∩" with a slash through it, denoted as ( A \cap B = \emptyset ). This indicates that two sets, ( A ) and ( B ), have no elements in common. Alternatively, some texts may simply state that sets ( A ) and ( B ) are disjoint without using a specific symbol.
Disjoint means they have no elements in common. The union is the set of elements containing all elements from both sets. Since there is no overlap, the union will have 5+7 elements. Therefore the answer is 12.
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)
The good real life example is the box of toys and the box of food. Imagine letting A be the box of toys and B be the box of food. Then, the intersection of those sets is empty.The example of disjoint set in mathematics is as followed:Let A = {1,2} and B = {3}. Then, A ∩ B = ∅
Yes,Because not all disjoint no equivalent other have disjoint and equivalent
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".
