Which equation demonstrates the associative property? a. –(33 + 4) = –33 + (–4) b. (–16 + 9) + (–19) = –16 + (9 + (–19)) c. (–5 + 11) + 3 = (11 + (–5)) + 3 d. 2 + (–24) = –24 + 2

answer: group b.

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 %
