Final answer:
The experimental probability of the next customer ordering a medium, sweetened tea is 1/9.
Step-by-step explanation:
To find the experimental probability that the next customer who orders tea orders a medium, sweetened tea, we need to know the total number of options for ordering tea and the number of times a medium, sweetened tea is ordered.
Let's assume that the café has 9 different options for ordering tea (3 sizes x 2 types) and each option is ordered with about the same frequency. This means that each option has a probability of 1/9 of being chosen.
Since we want to find the probability of ordering a medium, sweetened tea, and there are 9 options in total, the probability of ordering a medium, sweetened tea is 1/9. Therefore, the experimental probability is 1/9.
