Step-by-step explanation:
Let's recall that joint frequency is the number of times a combination of two conditions happens together. In the question, we're asked about the frequency that a student surveyed is a senior and wants to work in a park cleanup as a community service.
Thus, the joint frequency of being a senior and wanting to have a park cleanup. is 26 out of 200 surveyed students. We can write it as 26/200 or 13%.
