The Venn diagram above shows the data collected at a sandwich shop for the last six months with respect to the type of bread people ordered (sourdough or wheat) and whether or not they got cheese on their sandwich. Use this data to create a two way frequency table and answer the questions.
If [i]A=no cheese[/i] and [i]B=sourdough[/i], find the following probabilities.[br]9. P(B)[br]10. [math]P\left(A\cap B\right)[/math][br]11. [math]P\left(A\cap B'\right)[/math][br]12. [math]P\left(A'\right)[/math][br]13. If they serve 100 sandwiches at lunch one day, how many should they prepare with sourdough and no cheese?[br]14. [math]P\left(A\cup B\right)[/math][br]15. [math]P\left(A\cup B\right)'[/math]
16. If 3 out of 5 students eat school lunch then how many students would be expected to eat school lunch at a school with 750 students? [br][br]17. In a well developed and carried out survey it was found that 4 out of 10 students have a pair of [br]sunglasses. How many students would you expect to have a pair of sunglasses out of a group of 45 students? [br][br]18. Data collected at a local mall indicted that 7 out of 20 men observed were wearing a hat. How [br]many would you expect to have been wearing hats if 7500 men were to be at the mall on a similar day? [br]
