joint probability (複数形 joint probabilities)

1. The probability distribution of a random variable whose sample space is the Cartesian product of the sample spaces of its (at least two) component random variables.
2. The probability that two events will occur simultaneously.

   Given two events ${\displaystyle A}$ and ${\displaystyle B}$ in the same probability space with ${\displaystyle P(B)>0}$, the conditional probability of ${\displaystyle A}$ given ${\displaystyle B}$ is defined as the quotient of the unconditional joint probability of ${\displaystyle A}$ and ${\displaystyle B}$, and the unconditional probability of ${\displaystyle B}$.^WP
