Question

A florist sold bouquet of red roses to 15 of the first 20 customers who came into his shop.

1. What is the experimental probability that a random customer in that group bought a bouquet of red roses?

2. Based on the experimental probability, how many bouquets of red roses should the florist expect to sell on a day with 120 customers?

Answer 1

P = 15/20 = 3/4

Since 3/4 of the experimental group bought roses, we can estimate that 3/4 of the larger group would do so too.

3/4 * 120 = ______ people
