some sanitation workers sifted through some recycling and trash to see whether people had correctly sorted their plastic bottles. what is the probability that a randomly selected bottle is made of plastic #5 given that the bottle is correctly placed? simplify any fractions.

some sanitation workers sifted through some recycling and trash to see whether people had correctly sorted their plastic bottles. what is the probability that a randomly selected bottle is made of plastic #5 given that the bottle is correctly placed? simplify any fractions.

Answer

Explanation:

Step1: Calcular el total de botellas correctamente colocadas

Sumamos los valores de botellas correctamente colocadas para cada tipo de plástico: $5 + 2+17=24$.

Step2: Encontrar el número de botellas de plástico #5 correctamente colocadas

El número de botellas de plástico #5 correctamente colocadas es 17.

Step3: Aplicar la fórmula de probabilidad condicional

La probabilidad condicional $P(A|B)$ se calcula como $\frac{n(A\cap B)}{n(B)}$. Aquí, $A$ es el evento de que la botella sea de plástico #5 y $B$ es el evento de que la botella esté correctamente colocada. Entonces la probabilidad es $\frac{17}{24}$.

Answer:

$\frac{17}{24}$
