#1 The country of Chile covers 757,000 square miles of South America.
If the continent of South America is 6.9 x 106 square miles, what percent of South America's land area is Chile?
OA 0.12%
OB 9.1%
OC 11%
OD 91%

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 %
