Explanation:

4x + 10 + x = 180

4x + x + 10 = 180

5x + 10 = 180

5x + 10 - 10 = 180 - 10

5x = 170

5x / 5 = 170 / 5

x = 34

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 %
