What does "the probability that a randomly selected member prefers certain workouts" refer to?

The phrase "the probability that a randomly selected member prefers certain workouts" refers to the overall tendency or collective opinion among a group about their workout preferences. This is not about an individual’s specific choice but rather focuses on the general behavior of a population segment regarding their workout likes.

In this context, collective opinion encompasses the likelihood that any individual randomly chosen from the group will belong to a category that prefers specific workout types. This concept reflects a statistical perspective where we are interested in understanding what most people in the group think or prefer, rather than the isolated preference of a single individual.

The understanding of preferences in a population helps in various decision-making contexts, such as tailoring fitness programs to meet the needs of the majority, which is why collective opinion is the most appropriate interpretation in this scenario.
