Answer :

The amount of roses given out would be 300 roses in total.

The experimental probability that the next customer arriving at his shop will buy a bouquet of red roses is 0.75

How to determine the experimental probability that the next customer buys a bouquet of red roses?

The given parameters are:

Red roses = 15

Total  = 20

The experimental probability is then calculated using:

P = Red roses/Total

This gives

P = 15/20

Evaluate

P = 0.75

Hence, the experimental probability that the next customer arriving at his shop will buy a bouquet of red roses is 0.75
