Si a + b = ab, pero b + c = bc cuánto sería a + c, si a es la raíz cuadrada de 169 multiplicado por 2, b es la suma de la división de 15 sumando 12, y c es el resultado de los antiguos resultados de ab restando 16 ¿Cuánto es ac + ab?

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 %
