Experiment with 2+ events happening in sequence

Complete set of all possible outcomes

Down the leftmost column

Across the top row

Combine row outcome with column outcome

Right-hand side where branches end

Count all the endpoints

First item returned before selecting second

$P(\text{event}) = \frac{n(\text{event})}{n(S)}$

Both give the same sample space
