Fried Freddy's
Freddy loves fried food. His passion for the perfect fried food recipes led to him opening the restaurant Fried Freddy’s. His two main dishes are fish and chicken. Knowing he also had to open up his menu to people who prefer to have their food grilled instead of fried, he created the following menu board:
Fried Freddy’sChoose dish: Chicken or Fish
Choose cooking preference:Grilled or Fried
After being open for six months, Freddy realized he was having more food waste than he should because he was not predicting how much fish and chicken he should prepare in advance. His business friend, Tyrell, said he could help.

Luckily, Freddy uses a computer to take orders each day so Tyrell had lots of data to pull from. After determining the average number of customers Freddy serves each day, Tyrell created the following Venn diagram to show Freddy the food preference of his customers:
