Final answer:
The experimental probability that the next student Claire talks to will pick baseball is 19/57.
Step-by-step explanation:
To find the experimental probability that the next student Claire talks to will pick baseball, we need to use the number of students who said baseball was their favorite sport, divided by the total number of students surveyed.
There were 19 students who said baseball was their favorite sport, and 38 students who had other favorite sports.
So, the total number of students surveyed is 19 + 38 = 57.
Therefore, the experimental probability that the next student Claire talks to will pick baseball is 19/57, which can be written as the fraction 19/57.
