Bonjour communauté!! J’espère que vous allez bien! Moi ça va moyen haha j’aurai besoin de votre aide précieuse pour ce problème de mathématique s’il vous plaît!
Je vous en remercie énormément!

the correct answer is 5 6 and 7

step-by-step explanation: it is d

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 %
