Cho hai hàm f : R −→ R, g : R −→ R lần lượt xác định bởi f(x) = ax + b và g(x) = cx + d, hãy xác định a, b, c, d để f ◦ g = g ◦ f và
f(f(x)) = f(x) + 1, ∀x.

the answer is 2/54

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 %
