2.1.3.2.2 - Intersections
Intersection

The overlap of two or more events is symbolized by the character $\cap$.

$P(A \cap B)$ is read as "the probability of A and B."

## Example: Red King

What is the probability of randomly selecting a card from a standard 52-card deck that is a red card and a king?

There are 2 kings that are red cards: the king of hearts and the king of diamonds.

$P(red \cap king)=\dfrac{2}{52}=.0385$

$P(F \cap U)=\dfrac{3814}{12242}=0.312$
