what is the coefficient of x when (7+8x)-3(2+6x+2x^2)+9(1+3x+4x^2+12x ^3)-9(7-x^2-8x^3+13x^4) is simplified?

u dumb boi

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 %
