Part 1:
1. Data was taken for two hospitals for a one month period of time. Assume all patients had an equal chance of going to
either hospital and, on average, the patients that attended either hospital had about the same health histories. Fill in the
blanks on the 2-way table below:
Died
Survived
total
Hospital A
63
Hospital B
Total
79
784
2100
2. Build a Venn Diagram for the data in the completed table above. Label your ovals. Include the relevant numbers in
3. For the data provided in problem 1 (above), calculate the following probabilities:
a. P(Died) = _____
b. P(patient went to Hospital A) = ____
c. P(did not survive and was at hospital B) = ____
d. P(Survived given that the patient was at Hospital A) = ____
e. P(went to hospital A and survived OR went to hospital B and died) = ____
f. Which hospital would you rather go to? Justify your answer with at least two of your own probability statements (with
numbers) that “proves” your opinion is correct.
4. Build a tree diagram for the data above. Choose the first branches so that you can use your table to answer the
following probability statement: P(Died given that you went to Hospital B) = _____
Part 2:
The following probability statements are given:
P(green eyes) = 40/110
P(blue and male) = 15/110
P(male) = 40/110
P(female given that the person doesn’t have blue or green eyes) = 12/25
5. (6 points) Fill in the following table using the numbers from the probability statements above:
Blue eyes
Green eyes
Other colored eyes
total
Male
Female
total
6. Build a tree diagram for the data above. Make your first branches so that you can answer the following question:
P(Green eyes / male) = ____
7. Build a Venn diagram
8. Calculate the following probabilities:
a. P(female and blue eyes) = ____
b. P(other colored eyes given that the person is a male) = ____
c. P(male OR has green eyes) = _____
9. 5 different books will be displayed in the library window. How many different arrangements are there?
