Consider the hypothetical case that there were only two brands of juice on the market, company A and company B. 52% of the population drinks juice from company A (it is not known whether these people consume only juice A or if they also consume juice B). 51% of the population drinks juice of company B (again, it is not known how many of these people drink only juice B or if they drink both juice). However, it is known that 21% of the population does not drink juice. Based on these data, we can estimate that the percentage of the population that drinks juice from both companies is: (choose only one) a) 56%
