At $18.50 per gallon, what is the cost to paint a building that is 12 feet high, 61 feet long, and 32
feet wide if there are 220 square feet of windows? One gallon covers 190 square feet. Assume
that you cannot buy a fraction of a gallon of paint.

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 %
