Step-by-step explanation:

Given data

Although we are not given any two vital parameters that are needed to find the radius of a circle

The first is the circumference

And the second is the area

To find the radius with a given circumference we use

C=2πr

To find the radius with a given area we use

A=πr^2

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 %
