Math Problem Statement

The following table shows U.S. employment figures for 2014, broken down by educational attainment. All numbers are in millions, and represent civilians aged 25 years and over. Those classed as "not in labor force" were not employed nor actively seeking employment.

Find the probability that a person had a bachelor's degree or higher, given that the person was unemployed. Round your answer to two decimal pla

Solution

To solve this problem, we need to find the conditional probability that a person has a bachelor's degree or higher, given that they are unemployed.

The formula for conditional probability is:

P(AB)=P(AB)P(B)P(A|B) = \frac{P(A \cap B)}{P(B)}

Where:

  • P(AB)P(A|B) is the probability of event A happening given that event B has occurred.
  • P(AB)P(A \cap B) is the probability that both A and B happen (the intersection of A and B).
  • P(B)P(B) is the probability of event B happening.

Step 1: Define the events

  • Event AA: The person has a bachelor's degree or higher.
  • Event BB: The person is unemployed.

We are given that:

  • The total number of unemployed people is 6.86.8 million.
  • The number of unemployed people with a bachelor's degree or higher is 1.61.6 million.

Step 2: Calculate the conditional probability

Using the conditional probability formula:

P(Bachelor’s degree or higherUnemployed)=1.66.8P(\text{Bachelor's degree or higher} | \text{Unemployed}) = \frac{1.6}{6.8}

P(Bachelor’s degree or higherUnemployed)=0.2353P(\text{Bachelor's degree or higher} | \text{Unemployed}) = 0.2353

Step 3: Round the answer

Rounding the result to two decimal places:

P(Bachelor’s degree or higherUnemployed)=0.24P(\text{Bachelor's degree or higher} | \text{Unemployed}) = 0.24

Thus, the probability that a person has a bachelor's degree or higher, given that they are unemployed, is 0.24.

  1. What is the probability that a person with a high school diploma only is unemployed?
  2. How do you find the probability of being employed given a specific educational level?
  3. What is the probability that a randomly selected person is not in the labor force?
  4. How do you calculate the overall unemployment rate from this data?
  5. How can you use this data to estimate the employment rate by education level?

Tip: Conditional probability helps in analyzing real-life data by focusing on the occurrence of one event based on the knowledge of another.
