Probabilidad de eventos mutuamente excluyentes

Eventos mutuamente excluyentes

Si dos eventos son disjuntos, entonces la probabilidad de que ambos ocurran al mismo tiempo es 0. Si dos eventos son mutuamente excluyentes, entonces la probabilidad de que ocurra cualquiera es la suma de las probabilidades de que ocurra cada uno.

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.
