What is AUB in a Venn diagram?
The union of two sets A and B is a set that contains all the elements of A and B and is denoted by A U B (which can be read as “A or B” (or) “A union B”).
Which region in the Venn diagram represents the A ∩ B ∩ C?
The green region is A ∩ B ∩ ~C (those points in both A and B but not in C), while A ∩ ~B ∩ ~C is the red region. We shade the region A ∩ (B ∪ ~C) in a Venn diagram for three sets. These will be the points which are in the A circle, and either in the B circle or not in the C circle.
What is AnB?
Intersection The intersection of two sets A and B, written AnB, is the overlap of the two sets. Difference The difference of two sets A and B, written A
What does this ⊆ mean?
is a subset of
The symbol “⊆” means “is a subset of”. The symbol “⊂” means “is a proper subset of”. Example. Since all of the members of set A are members of set D, A is a subset of D. Symbolically this is represented as A ⊆ D.
What is AUC math?
AUC is the area under curve between the ROC line and the x-axis that shows 1-specificity, and it is proportional to precision, recall, accuracy, and F1-scores but this is a marginal measure based on the way that you calculate the ROC curve.
What does a ∩ b )’ mean?
A intersection B is a set that contains elements that are common in both sets A and B. The symbol used to denote the intersection of sets A and B is ∩, it is written as A∩B and read as ‘A intersection B’. The intersection of two or more sets is the set of elements that are common to every set.
What does the shaded region of a graph represent?
The solutions to a linear inequality can be shown as a shaded region that represents the ordered pairs which make the inequality true. The boundary line of the region is the graph of the related equation. the ordered pairs which make the inequality true.
What is ANB in Venn diagram?
We use to denote the universal set, which is all of the items which can appear in any set. This is usually represented by the outside rectangle on the venn diagram. A B represents the intersection of sets A and B. This is all the items which appear in set A and in set B.
