Final answer:
Determining the probability of a consumer having a specific choice score in the flexed arm condition requires statistical data or a probability distribution function, which are not provided in the question.
Step-by-step explanation:
Without additional context about the "flexed arm condition" or information on how the "choice score" is distributed, calculated, or determined, it is not possible to calculate the probability that a consumer has a specific choice score. To determine probabilities related to choice scores, one would need statistical data or a probability distribution function indicating how choice scores are assigned or occur among consumers in the flexed arm condition. In statistics, such probabilities are typically derived from understanding the mean, standard deviation, and the shape of the distribution curve, such as being normally distributed or having some other form.
