Suppose the number of requests for assistance received by a 24-hour towing service is on average 4 per day, and the the number of requests can be modeled by a Poisson process. Suppose further that the number of requests during any non-overlapping intervals are independent of one another.
(a) On a given day, what is the probability that the towing service will receive no more than 3 requests for assistance?

Ответ:
The formula for the circumference of a circle is
C = 2π·r
or
r = C/(2π)
The radius r of cylinder A is
r = (4π)/(2π) = 2
The formula for the area of a circle is
A = π·r²
or
r = √(A/π)
The radius of cylinder B is
r = √(9π/π) = 3
The dimensions of cylinder A must be multiplied by 3/2 to produce the corresponding dimensions of cylinder B.
