Question

the following table represents the highest educational attainment of all adult residents in a certain town. if a resident who is under 40 years old is chosen at random, what is the probability that they have only completed some college? round your answer to the nearest thousandth.

	age 20 - 29	age 30 - 39	age 40 - 49	age 50 & over	total
some college	945	1226	672	2334	5177
bachelors degree	1808	1556	459	2127	5950
masters degree	901	507	425	816	2649
total	5278	3939	2550	7130	18897

Explanation:

Step1: Find total under 40

Sum Age 20-29 and 30-39 totals: $5278 + 3939 = 9217$

Step2: Find some college under 40

Sum some college in 20-29 and 30-39: $945 + 1226 = 2171$

Step3: Calculate probability

Divide some college under 40 by total under 40: $\frac{2171}{9217} \approx 0.234$

Answer:

0.234
