The number of hits to a website follows a Poisson process. Hits occur at the rate of 0.4 per minute between 7:00 P. M. and 10:00 P. M. Given below are three scenarios for the number of hits to the website. Compute the probability of each scenario between 8 : 27 P. M. and 8:31 P. M. Interpret each result. (a) exactly seven (b) fewer than seven (c) at least seven

a) Probability of getting exactly 7 hits = 0.001075

b)  Probability of getting fewer than seven = 0.999

c) Probability of getting at least seven hits = 0.001

Step-by-step explanation:

The process is a Poisson process.

Rate,

The probability is to be calculated between 8:27 PM and 8:31 PM

t = 4

If the number of hits is represented by X

a) Probability of getting exactly 7 hits

b) Probability of getting fewer than seven

P(X < 7) = 0.999

c) Probability of getting at least seven hits

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following
