Poisson distribution and binomial distribution questions

Click For Summary
SUMMARY

The discussion centers on the definitions and applications of the Poisson and binomial probability distributions. The Poisson distribution is defined with a mean (μ) for modeling the number of events in a fixed interval, while the binomial distribution describes the probability of achieving x successes in n independent trials with a success probability p. Specific examples include calculating the probability of finding no more than 3 defective nails from a sample of 400, and determining the likelihood of exactly three lawn mowers being hired from a mean of 4.5.

PREREQUISITES

Please help with this thanks :)

1.
(a) Define the Poisson probability distribution with mean μ.

(b) Write down the binomial distribution for x successes in n independent trials each with probability p of success.

(c) On average, 0.15% of the nails manufactured at a factory are known to be defective. If a random sample of 400 nails is inspected, what is the probability of there being no more than 3 defective nails?

4.
(a) Define the Poisson probability distribution with mean p.

(b) A tool hire shop has six lawn mowers which it hires out on a daily basis.The number of lawn mowers requested per day follows a Poisson probability distribution with mean 4.5. Find the probability that:

(i) exactly three lawn mowers are hired out on anyone day;
(ii) all lawn mowers are in use on anyone day.
