. Una distribución de probabilidades permite organizar todos los resultados posibles de
una variable aleatoria junto con sus correspondientes probabilidades de ocurrencia.
El valor esperado E(x) de una variable aleatoria discreta se calcula multiplicando
cada valor que esta puede asumir por su probabilidad de ocurrencia y luego
sumando los productos.
La siguiente tabla muestra la distribución de probabilidades correspondiente al
tiempo (en minutos) que demora una computadora en recuperarse luego de una
falla. ¿Cuál es el tiempo más probable de espera para volver a utilizar la
computadora?
Tiempo (x) 2.0 3.0 4.0 5.0
Probabilidad P(x) 0.10 0.30 0.10 0.50

Mary beth used the mapping rule to find the coordinates of a point that had been rotated 90° counterclockwise around the origin. examine the steps to determine whether she made an error. m (3, –6) is rotated 90° counterclockwise. (x, y) → (–y, x) 1. switch the x- and y-coordinates: (6, –3) 2. multiply the new x-coordinate by –1: (6(–1), –3) 3. simplify: (–6, –3) .
