Geometry . so i understand that the sum of ab • ap should equal cd • cp but how would i go about finding the value of x? i could put random numbers in the equation until the sums were equal but i figure there's a simpler way of doing this.

y -5 = (-1/4)(x + 8)

step-by-step explanation:

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 %
