An alcohol awareness task force at a Big-Ten university sampled 200 students after the midterm to ask them whether they went bar hopping the weekend before the midterm or spent the weekend studying, and whether they did well or poorly on the midterm. The following result was obtained.

One hundred adults were randomly sampled and took their BMI and categorize them as Underweight, Normal Weight and Overweight. The data is summarized in the following table. If one of the hundred aults is randomly selected: a) What is the probability that they are 56+ or overweighted? b) What is the probability that they are underweighted or normal weighted? c) Is it correct to say that a randomly selected adult is 1.2 times as likely to be an overweighted as underweighted? Justify your answer.

Use the data in the following table that shows results from a polygraph (lie detector) conducted by researchers Charles R. Honts and Gordon H. Barland. In each case, it was known if the subjects lied or did not lie, so the table indicates when the polygraph was correct. If two different subjects are randomly selected without replacement, find the probability that they both lied.
A manufacturer received an order of 105 computer chips. Unfortunately, 5 of the chips are defective. To test the shipment, the quality-control engineer randomly selects 5 chips from the box of 105 and tests them. What is the probability of obtaining 2 defective chips?

In a particular survey of internet users, 3575 respondents say that they use social networking sites and 1348 respondents say that they do not use social networking sites. What is the probability that a randomly selected person uses a social networking site? Does that result suggest that it is likely (with a probability of 0.5 or greater) for someone to use social networking sites? The probability that a randomly selected person uses a social networking site i
A random sample of cars was classified by size: small, medium, and large, and by region of manufacture: Asia, Europe, and North America. The following data resulted: Size of Car Small Mid-size Total Region of Manufacture Asia 92 54 2 148 Europe 19 17 40 North America Total 26 53 36 115 137 124 42 1. Among the cars manufactured in Asia, what is the probability of selecting a large car? 2. What is the probability of selecting a car that is mid-size or manufactured in North America? 3. What is the probability of selecting a car manufactured in Europe? If three cars are selected at random and without replacement, what is the probability they are all small cars manufactured in Asia? 4. Are 'region of manufacture' and 'size of car' independent or dependent? Justify your conclusion mathematically.
The quality control department examines all the products returned to a store by customers. An examination of the returned products yields the following assessment: 5% are defective and not repairable, 45% are defective but repairable, 35% have small surface scratches but are functioning properly, and 15% have no problems. Compute the following probability for a random sample of 20 returned products. Of the 20 returned products, 6 or more are defective and not functioning properly
