Solution
Primero, sumemos el número total de adultos que tienen solo un diploma de secundaria y aquellos que tienen algo de universidad pero no un título universitario.
Para los que tienen solo un diploma de secundaria: 436 (20-29) + 953 (30-39) + 857 (40-49) + 565 (50 y más) = 2811
Para los que tienen algo de universidad: 1365 (20-29) + 987 (30-39) + 765 (40-49) + 2464 (50 y más) = 5581
Ahora, sumemos estos dos resultados para obtener el total de adultos con un diploma de secundaria o algo de universidad: 2811 + 5581 = 8392
El número total de adultos en la ciudad es: 3073 (20-29) + 3447 (30-39) + 2699 (40-49) + 6149 (50 y más) = 15368
La probabilidad de que un adulto elegido al azar tenga un diploma de secundaria o algo de universidad, pero no un título universitario, es: 8392 / 15368
Dividimos y redondeamos el resultado a la milésima más cercana: 8392 / 15368 ≈ 0.546
Por lo tanto, la probabilidad es aproximadamente 0.546.
