Symbols:Q

Probability

 * $$q$$

Used in conjunction with the general probability $$p$$:
 * $$q = 1 - p$$

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


 * $$0 \le q \le 1$$

and
 * $$p + q = 1$$

The LaTeX code for $$q$$ is q.

The Set of Rational Numbers

 * $$\Q$$

The set of rational numbers.

The LaTeX code for $$\Q$$ is \mathbb{Q} or \Q.

The Set of Non-Zero Rational Numbers

 * $$\Q^*$$

The set of non-zero rational numbers:
 * $$\Q^* = \Q - \left\{{0}\right\}$$.

The LaTeX code for $$\Q^*$$ is \mathbb{Q}^* or \Q^*.

The Set of Non-Negative Rational Numbers

 * $$\Q_+$$

The set of non-negative rational numbers:
 * $$\Q_+ = \left\{{x \in \Q: x \ge 0}\right\}$$.

The LaTeX code for $$\Q_+$$ is \mathbb{Q}_+ or \Q_+.

The Set of Strictly Positive Rational Numbers

 * $$\Q_+^*$$

The set of strictly positive rational numbers:
 * $$\Q_+^* = \left\{{x \in \Q: x > 0}\right\}$$.

The LaTeX code for $$\Q_+^*$$ is \mathbb{Q}_+^* or \Q_+^*</tt>.
