URGENTE se lo agradezco 1.- Se arrojan un dado cúbico justo y un dado tetraédrico justo. La variable aleatoria discreta S es definido como la diferencia positiva de los números de los dos dados.
a.- Construya la distribución de probabilidad de S como: i.- una tabla de valores ii.- un gráfico de barras iii.- una función por partes.
b.- Por lo tanto, encuentre las probabilidades: i.- P (S> 2) ii.- P (S es como máximo 3) iii.- P (S≤4/S> 2).

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is

idk

step-by-step explanation:

sorry

sorry, but im pretty sure its a now that i look at it
