2,000.h for h = 0.004
2,000 h =

Step-by-step explanation:

We need to find h for the following condition.

2,000×h = 0.004

Dividing both sides by 2000

So, the value of h is equal to .

17 1/3

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 %
