Example 35
The first 50 cases, which we know to be examples of setosa, are placed in Group
number 3 with a probability of 1, so Group number 3 clearly contains setosa flowers.
Cases 51 through 100 fall mainly into Group number 2, so Group number 2 clearly
contains versicolor flowers. Similarly, although the preceding figure does not show it,
cases 101 through 150 are assigned mainly to Group number 1, so Group number 1
clearly contains virginica flowers.
