factor out the gcf of three terms, then complete the factorization of 6x^3 + 6x^2 - 120x
possible answers are:
6x^2(x+1)-120x
6x(x+4)(x-5)
6x(x-4(x+5)

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 %
