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
