Since 1903, the NL has played the AL in the World Series. The WS is usually won by the team winning a best of 7 series. The table below shows the number of games played to win each series.

Number of games                  Number of Series Won

4 games                                  17 series

5 games                                  24 series

6 games                                  21 series

7 games                                  33 series

8 games                                  5 series

Is this experimental or theoretical probability?
