En una plaza Lucio camina en tramos rectos, a partir del asta bandera, en un punto cambia la dirección girando 150° a su
izquierda, avanza 64 metros y se detiene. Para regresar al asta tiene
que girar 75º a la izquierda, ¿A qué distancia se encuentra del
punto inicial?

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
