Help plz my teacher didnt teach this correctly

we have:

(xy²)³ = x³.(y²)³ = x³y⁶ (1)

(xy³)² = x².(y³)² = x²y⁶ (2)

from (1)(2) => (xy²)³ isnt the same as (xy³)²

25% is the answer

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 %
