A normal population has mean \( \mu=62 \) and standard deviation \( \sigma=17 \). (a) What proportion of the population is greater than 103 ? (b) What is the probability that a randomly chosen value will be less than 79 . Round answers to four decimal places. Part 1 of 2

En un colegio están midiendo la cantidad de inasistencia diaria a un curso de 45 alumnos, sea \( x \) una variable aleatoria que indica cuántos alumnos han faltado en un dia. A continuación se presenta la función de cuantia: \( P(X=x)=\left\{\begin{array}{l}\frac{(x+1)}{145} \\ \frac{(x+2)^{2}}{145} \\ 0.20\end{array} \quad x=0,1,2\right. \) Determine la dispersión lineal de alumnos que faltan un día.

In a survey of 258 professional athletes, it was found that 122 of them owned a convertible, 117 of them owned a giant screen TV, and 113 owned a sporting goods store. 21 owned a convertible and a store, 44 owned a TV and a store, and 66 owned a covertible and a TV. 10 owned all three items. 1. How many athletes did not own any of the three items? 2. How many owned a covertible and a TV, but not a store? 3. How many athletes owned a convertible or a TV? 4. How many athletes owned exactly one type of item in the survey? 5. How many athletes owned at least one type of item in the survey? 231 6. How many owned a TV or a store, but not a convertible?
