As claimed on the website of the National Federation of Fish Fisheries, “Fish and chips are the undisputed National dish of Great Britain »(1). In a country with 67 million inhabitants (including Northern Ireland), it is said that 382 million meals from fish & chip shops are served every year, including 167 million only fish and chips meals. 80% of people visit one of the 10,500 fish and chip shops at least once a year, while 22% visit them at least once a week!
For every question, show the details of your calculations and answer the question with a sentence written in English. Don’t forget to write numbers with English rules!
1) If we pick a British citizen who goes to a fish & chip shop, what is the probability that the meal they choose is a fish and chip meal?
2) What is the average number of meals served by a single fish and chip shop in the UK every year?
3) What is the average number of fish and chip meals ordered by a single British fish and chip shop customer every year?
4) Which of the following choices completes correctly the sentence? Justify your answer.

□ Can be any number, except 0.
□ Is precisely 3.
□ Is between 25 included and 35 included.
