The graph represents the relationship between the number of rocks a child collects, r, over a number of weeks, w. Which function can be used to determine the number of rocks, r, a child will collect after w weeks? r = 15w + 5 r=115w+5 r = 5w + 15 r=15w+15

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 %
