Which pair of events is dependent?

Dependent events means they DEPEND on each other. If 1 events were to change, then the other would also change.

Step-by-step explanation:

If you are tossing 2 coins, those coins do not depend on each other. If 1 outcome changes, the other will not be affected.

If you are tossing the same coin you still have a 50/50 chance each time so these are not dependent.

Drawing 2 cards WITH replacement will not change the probability so these are also not dependent.

Picking 2 billiard balls WITHOUT replacement IS dependent. If you were to pick a certain ball, that ball is no longer available so the probability can change because it depends on what ball is chosen first.

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 %
