Estimating Overlapping Preferences for Coffee and Tea

In a survey conducted among 100 individuals, two questions were posed: 1. Do you enjoy tea? 2. Do you enjoy coffee? 70% of participants expressed a preference for coffee, while 80% indicated they enjoyed tea. Only 10% of the participants mentioned they did not like either beverage. Using this data, determine the maximum and minimum possible percentages of the population that enjoy both tea and coffee.
