Final answer:
To calculate the probability, we would need the total number of survey respondents and the number of respondents who are older than 40 and shop at the store.
Step-by-step explanation:
In order to determine the probability that a survey respondent who is older than 40 shops at the store, we need to know the total number of survey respondents and the number of respondents who are older than 40. Without this information, we cannot calculate the probability. However, if we had the required data, we could calculate the probability by dividing the number of respondents who are older than 40 and shop at the store by the total number of respondents. For example, if there are 200 survey respondents and 50 of them are older than 40 and shop at the store, the probability would be 50/200 = 0.25, or 25%.
