We want P(age 30–49 | bachelor's or master's) = (number with bachelor's or master's and age 30–49) / (total with bachelor's or master's).
Number aged 30–49 with bachelor's or master's = 407+511+290+496 = 1704.
Total with bachelor's or master's = 3562+2300 = 5862.
Probability = 1704 / 5862 ≈ 0.290686 ≈ 0.291 (to the nearest thousandth).
Number aged 30–49 with bachelor's or master's = 407+511+290+496 = 1704.
Total with bachelor's or master's = 3562+2300 = 5862.
Probability = 1704 / 5862 ≈ 0.290686 ≈ 0.291 (to the nearest thousandth).
