Studdy Solution
STEP 1
Assumptions
1. The table represents the highest educational attainment of all adult residents in a certain town.
2. We are interested in the probability of a resident with a master's degree being aged 50 or over.
3. The total number of residents with a master's degree is given in the table.
4. The number of residents with a master's degree aged 50 or over is given in the table.
STEP 2
First, we need to identify the total number of residents with a master's degree, which is the sum of residents with a master's degree across all age groups.
STEP 3
From the table, we find the total number of residents with a master's degree.
STEP 4
Next, we need to identify the number of residents with a master's degree who are aged 50 or over.
STEP 5
From the table, we find the number of residents with a master's degree aged 50 or over.
STEP 6
Now, we can calculate the probability that a resident with a master's degree is aged 50 or over by dividing the number of residents with a master's degree aged 50 or over by the total number of residents with a master's degree.
STEP 7
Plug in the values to calculate the probability.
STEP 8
Calculate the probability.
STEP 9
Round the probability to the nearest thousandth.
The probability that a resident with a master's degree is aged 50 or over is approximately 0.437.
