One independent survey showed that 70% on people asked like coffee. Another independent survey showed that 80% of people like tea. What is the upper and lower bound of peoples who likes both coffee and tea
The best case cenario is that all 70% of the people that like tea also like coffe (the other 10% don't),
so the upper bound is 70%. The worst case cenario is that from the 70% that like coffe, only 80% of them
like tea, so the lower bound is 70%*80% = 56%.
