Answer:
72.06% probability that the plant had white flowers.
27.94% probability that the plant had purple flowers.
Explanation:
The experimental probability is the number of desired outcomes divided by the number of total outcomes, from an experiment.
In this problem:
The experiment is the number of plants counted.
There are 601 + 233 = 834 plants.
601 have white flowers
601/834 = 0.7206
72.06% probability that the plant had white flowers.
233 have purple flowers
233/834 = 0.2794
27.94% probability that the plant had purple flowers.
