1. Given that x = -2, the expression 2x2 + 5x + 8
is equivalent to:
2 + 2
1) 2x +9-10/x+2
2) 2x +1+6/x+2
3) 2x^2 +7/x+2
4) 2x^2 +y/x+2

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 %
