a package of party favors contains 14 favors, of which 7 are glitter balls. what is the probability that a randomly selected favor will be a glitter ball? write your answer as a fraction or whole number. p(glitter ball) =
Answer
Explanation:
Step1: Identificar el número de casos favorables y totales
El número de casos favorables (glitter balls) es 7, y el número total de casos (favors) es 14.
Step2: Aplicar la fórmula de probabilidad
La fórmula de probabilidad es $P(A)=\frac{\text{casos favorables}}{\text{casos totales}}$. Entonces $P(\text{glitter ball})=\frac{7}{14}$.
Step3: Simplificar la fracción
$\frac{7}{14}=\frac{1}{2}$.
Answer:
$\frac{1}{2}$
