1. What makes the binomial distribution unique? What are its characteristics?
Give a real-world example of a distribution of data that would
be considered binomial.
2. Solve the following problem:
About 30% of adults in United States have college degree.
(probability that a person has college degree is p = 0.30).
If N adults are randomly selected, find probabilities that
1) exactly X out of selected N adults have college degree
2) less than X out of selected N adults have college degree
3) greater than X out of selected N adults have college
degree
Choose your numbers for N and X.

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. Fifty-eight percent of U.S. adults oppose hydraulic fracturing (fracking) as a means of increasing the production of natural gas and oil in the United States. You randomly select five U.S. adults. Find the probability that the number of U.S. adults who oppose fracking as a...

Question 12 of 13 > According to CDC estimates, more than two million people in the United States are sickened each year with antibiotic-resistant infections, with at least 23,000 dying as a result. Antibiotic resistance occurs when disease-causing microbes become resistant to antibiotic drug therapy. Because this resistance is typically genetic and transferred to the next generations of microbes, it is a very serious public health problem. Of the three infections considered most serious by the CDC, gonorrhea has an...
