Use the table to answer questions (1) to (11).
- Use the information in the table to fill in the blanks in the row and column totals.
- How many people (male and female) got married in the State?
- If a person that was married was randomly chosen, what is the probability that the person was a female less than 20 years old? Express your answer as a percent rounded to the nearest whole percent.
- If a person that was married was randomly chosen, what is the probability that the person was a male less than 20 years old? Express your answer as a percent rounded to the nearest whole percent.
- If a person that was married was randomly chosen, what is the probability that the person was between the ages of 25 and 34? Express your answer as a percent rounded to the nearest whole percent.
- Of the people over the age of 45 who got married, what percentage was female? What percentage was male? Express your answer as a percent rounded to the nearest whole percent.
- Given that a person married was less than twenty years old, what is the probability that the person was male?
- Given that a person married was female, what is the probability that the person was between the ages of 35 and 44?
- If a person that was married was randomly chosen, what is the probability that the person was over the age of 45 or female?
- If a person that was married was randomly chosen, what is the probability that the person is male and between the ages of 25 and 34
- Describe two events, A and B, which are mutually exclusive for the number of marriages in the State. Calculate the probability of each event, and the probability of A or B occurring.
PART 2:
There are data that give the relative frequency probabilities of various types of accidents (such as being killed by lightning, by a shark bite, or by falling airplane debris).
Choose two types of fatal accidents and research the relative frequency probabilities of each. Compare and discuss your findings. Were you surprised by the results? Why or why not? Your answers should be a minimum of three complete sentences. Be sure to include your references.
