Symbols:P

General Prime Number

 * $$p$$

Used to denote a general prime number.

The LaTeX code for $$p$$ is p.

Probability

 * $$p$$

Used to denote a general probability.

As such, $$p$$ is a real number such that:


 * $$0 \le p \le 1$$

The LaTeX code for $$p$$ is p.

Power Set
$$\mathcal{P} \left({S}\right)$$ is the power set of the set $$S$$.

It is defined as: $$\mathcal{P} \left({S}\right) = \left\{ {T: T \subseteq S}\right\}$$.

$$\mathfrak {P} \left({S}\right)$$ is an alternative notation, but the "fraktur" font, of which $$\mathfrak {P}$$ is an example, is falling out of use, probably as a result of its difficulty in being both read and written.

The LaTeX code for $$\mathcal{P} \left({S}\right)$$ is \mathcal{P} \left({S}\right).

The LaTeX code for $$\mathfrak {P} \left({S}\right)$$ is \mathfrak {P} \left({S}\right).

Poisson Distribution

 * $$X \sim \operatorname{Pois} \left({\lambda}\right)$$

or
 * $$X \sim \operatorname{Poisson} \left({\lambda}\right)$$

$$X$$ has the Poisson distribution with parameter $$\lambda$$.

The LaTeX code for $$X \sim \operatorname{Pois} \left({\lambda}\right)$$ is X \sim \operatorname{Pois} \left({\lambda}\right).

The LaTeX code for $$X \sim \operatorname{Poisson} \left({\lambda}\right)$$ is X \sim \operatorname{Poisson} \left({\lambda}\right).

Probability Measure

 * $$\Pr$$

The LaTeX code for $$\Pr$$ is \Pr.

Probability Mass Function

 * $$p_X \left({x}\right)$$

The LaTeX code for $$p_X \left({x}\right)$$ is p_X \left({x}\right).
