The number of visits to a website is known to have a Poisson distribution with a mean of 10 visits per minute.
a) What is the probability distribution for x, the number of visits per minute? p(X)=??
b) What is the probability that the number of visits per minute is less than or equal to 10? (Round your answer to three decimal places.)
c) What is the probability that the number of visits per minute is greater than 14? (Round your answer to three decimal places.)
d) Within what limits does Tchebysheff's Theorem suggest you would expect the number of visits to this website to lie at least 75% of the time? (Round your answer up to the nearest whole number.)

If we assume the number of visits to a blog has a Poisson distribution, with average of 99 visits per second. Let X be the waiting time until one visit to the blog: a) What distribution does X follow? State the probability density function of x and give an appropriate graphing rage of x for f(x) b) What is the probability that at least 50 seconds are needed until one visit occur?

Find the indicated probabilities using the geometric distribution, the Poisson distribution, or the binomial distribution. Then determine if the events are unusual. If convenient, use the appropriate probability table or technology to find the probabilities. The mean number of births per minute in a country in a recent year was about seven. Find the probability that the number of births in any given minute is (a) exactly five, (b) at least five, and (c) more than five. (a) P(exactly five)...
