Answer:

106.34%  

Step-by-step explanation:

hay 24 personas en total (11 mujeres+13 hombres)

la probabilidad para que uno de los alumnos es un hombre es 13/24 (porque hay 13 hombres en la clase)

Entonces, si uno hombre está elegido, quedan 12 hombres, así que, la probabilidad si es un hombre es 12/23 (porque una persona ya está elegido y quedan 23 personas)

la probabilidad es 13/24+12/23=587/552=106.34%  (Redondeado a la décima más cercana)

(lo siento mi español no es perfecto)

mote1985 [20]

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

y =f(x) =   - 2x + 4

_________________________________

f( - 4) =  - 2( - 4) + 4

f( - 4) = 8 + 4

f( - 4) = 12

_________________________________

f(0) =  - 2(0) + 4

f(0) = 0 + 4

f(0) = 4

_________________________________

f(5) =  - 2(5) + 4

f(5) =  - 10 + 4

f(5) =  - 6

_________________________________

Range = { 12 , 4 , -6 }

Thus the correct answer is (( A )) .
