1pc 11. A hardware store rents vacuum cleaners that customers may use for
part or all of a day before returning. The store charges a flat fee plus an
hourly rate. Write a linear function for the total rental cost, f(x), of a vacuum
cleaner after x hours of rental. *

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 %
