ira [324]

Answer:

The emperical probability of being a plant with white flower is

$\dfrac{639}{919}\approx 0.695$

The emperical probability of being a plant with purple flower is

$\dfrac{280}{919}\approx 0.305$

Step-by-step explanation:

There are

639 plants with white flowers
280 plants with purple flowers
919 plants in total.

The empirical probability of an event is the ratio of the number of outcomes in which a specified event occurs to the total number of trials, not in a theoretical sample space but in an actual experiment.

The emperical probability of being a plant with white flower is

$\dfrac{639}{919}\approx 0.695$

The emperical probability of being a plant with purple flower is

$\dfrac{280}{919}\approx 0.305$
