"WebTo count the number of possible sets C, we use that C is symmetric, meaning, if ( b, c) ∈ C then also ( c, b) ∈ C. Now, let [ A] 2 be the collection of subsets of A of size 2. Note [ A] 2 consists of subsets rather than ordered pairs. Given any D subset of [ A] 2, we can associate to it a set C by setting C = { ( b, c) ∣ { b, c } ∈ D }. " - Binary symmetric

A symmetric relation is a type of binary relation. An example is the relation "is equal to", because if a = b is true then b = a is also true. Formally, a binary relation R over a set X is symmetric if: $${\displaystyle \forall a,b\in X(aRb\Leftrightarrow bRa),}$$ where the notation $${\displaystyle aRb}$$ means … See more In mathematics • "is equal to" (equality) (whereas "is less than" is not symmetric) • "is comparable to", for elements of a partially ordered set • "... and ... are odd": See more • A symmetric and transitive relation is always quasireflexive. • A symmetric, transitive, and reflexive relation is called an equivalence relation. • One … See more • Commutative property – Property of some mathematical operations • Symmetry in mathematics See more WebIn a binary tree data structure, each node has two subtrees, a left subtree and a right subtree which can be an empty subtree as well.

In this model, a transmitter wishes to send a bit (a zero or a one), and the receiver will receive a bit. The bit will be "flipped" with a "crossover probability" of p, and otherwise is received correctly. This model can be applied to varied communication channels such as telephone lines or disk drive storage.
