Question 12 of 25 What is the surface area of a sphere with radius 3?
A. 377 units2
B. 1877 units2
O c. 367 units
D. 97 units

both equations and proportions are better.

idk

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 %
