An urn has n−3 green balls and 3 red balls. Draw L balls with
replacement. Let B denote the event that a red ball is seen at
least once. Find P(B) using the following methods.
42 1. Experiments with random outcomes
(a) Use inclusion-exclusion with the events Ai = {ith draw is red}.
Hint. Use the general inclusion-exclusion formula from Fact 1.26
and the binomial theorem from Fact D.2.
(b) Decompose the event by considering the events of seeing a red exactly k times, with k = 1,2,...,L.
(c) Compute the probability by considering the complement Bc

The decision of a judge over a case can become a means to bind others in similar disputes in the future. For example, a decision of the Federal Court over a case can bind the lower courts and a decision of a High Court can bind the Sessions Court or the Magistrates Courts.
1. How could the judges in the lower courts overcome the doctrine of binding judicial precedents?
2. If the law in the country can be developed through judicial precedents, why is there a need for statutory law?
Explain both questions in detail. (Use your own words, don't use same chegg answers and don't copy from internet source)

1) Describe in detail the measurement of GDP. Document what GDP does not measure. Is GDP a good measure of the standard of living and the quality of life of a society? Justify your answer. How would you suggest improving GDP to better measure standard of living and quality of life or would you suggest an entirely measure or set of measure be developed? Explain.

Collect data from 30 people from your work, school, neighborhood, family, or other group. Ask a quantitative question, such as, “How many pets do you have?” or “How many college classes have you taken?” Explain your population, sample, and sampling method and what level of measurement your data is (nominal, ordinal, interval, or ratio). Use technology ( Excel) to create a Histogram of your data and explain the shape of the distribution (bell-shaped, uniform, right-skewed, or left-skewed) and possible reasons why the distribution is this shape. Explain the importance of this data, what you find interesting about the data, and why the public should know. Look up a newspaper, e-pub, or journal article that confirms or denies the results of your small study.
Please explain briefly.
