The following table represents the highest educational attainment of all adult residents in a certain town. If a resident who is aged 30-39 is chosen at random, what is the probability that they have completed a bachelor's degree and no more? Round your answer to the nearest thousandth.
Age 20-29	Age 30-39	Age 40-49	Age 50 & over	Total
High school only	1288	392	364	784	2828
Some college	          1017 956	658	2350	4981
Bachelor's degree	       1488	1238	457	1626	4809
Master's degree	829	621	612	1317	3379
Total	4622	3207	2091	6077	15997


To find the probability that a randomly chosen resident aged 30-39 has completed a bachelor's degree and no more, we will use the following steps:

### Step 1: Identify the relevant data.
- The number of residents aged 30-39 who have completed a bachelor's degree is **1238**.
- The total number of residents aged 30-39 is the sum of all categories for that age group: 
  \[
  392 + 956 + 1238 + 621 = 3207
  \]

### Step 2: Calculate the probability.
The probability is given by the ratio of the number of residents aged 30-39 who have completed a bachelor's degree to the total number of residents aged 30-39:
\[
P(\text{Bachelor's degree only}) = \frac{1238}{3207}
\]

Let's calculate that value.

The probability that a randomly chosen resident aged 30-39 has completed a bachelor's degree and no more is approximately **0.386** (rounded to the nearest thousandth).
