Suppose that in a senior college class of 500 students, it is found that 200 smoke, 233 drink alcoholic beverages, 194 eat between meals, 103 smoke and drinkalcoholic beverages, 66 eat between meals and drink alcoholic beverages, 83 smoke and eat between meals, and 35 engage in all three of these bad healthpractices. If a member of this senior class is selected at random, find the probability that the student (a) smokes but does not drink alcoholic beverages; (b) eatsbetween meals and drinks alcoholic beverages but does not smoke; (c) neither smokes nor eats between meals.(a) P(smokes but does not drink alcoholic beverages) =(Type an integer or a decimal. Do not round.)(b) P(eats between meals and drinks alcoholic beverages but does not smoke) =(Type an integer or a decimal.

For a particular species of wolf, 48% are female, 30% hunt in medium-sized packs, and 10% are both female and hunt in medium-sized packs What is the probability of selecting a wolf that is female, given that it hunts in a mediumsized pack?
5. A manufacturer of cell phones purchases batteries from a vendor. It is not uncommon to receive defective batteries from this vendor, thus whenever a shipment is received, a sample of batteries is inspected. For this month's shipment, a random sample of 280 batteries is selected and each battery is inspected. If the proportion of defective batteries sampled is more than 1.5%, the entire shipment will be returned to the vendor. What is the probability that this month's shipment will be returned if the true proportion of defective batteries is 4%?
A company did a study of available vacation time for their staff employees over the past years. They determined the probability a staff employee selected at random has 2 weeks’ vacation was 45%, 1 week vacation 10%, 3 weeks’ vacation 20%, and more than 3 weeks’ vacation was 25%. The company randomly selects 20 employees. What is the probability that out of the 20 selected, at least 2 workers have 1 week vacation time?

(b) Find the probability of one student selected is full-time, that should be female.

4. According to the Red Cross Blood Organization, the blood type most requested by hospitals is type O. About 45% of the North American population has blood type O. a) If 4 blood donors are selected at random, create a probability distribution histogram to show the probability of x, where x represents the number of donors with blood type O. b) If 7 blood donors are selected at random, what is the probability that exactly 3 of them will have blood type O. c) If 10 blood donors are selected at random, what is the probability that exactly 6 will have other blood types? d) If 15 blood donors are selected at random, what is the probability that at least one willI have blood O?
10) According to the American Academy of Ophthalmology, there is a 45% chance that someone will have brown eyes. What is the probability that all of the next seven people selected will have brown eyes?
3. A study conducted at a large hospital found that 27.8 percent of all patients admitted to the hospital's ICU remained in the ICU for less than 24 hours. (A) If 8 patients are selected at random from the ICU patients at the hospital, what is the probability that 2 or fewer of them remained in the ICU for less than 24 hours? (B) Suppose that 20 patients are selected at random from the ICU patients at the hospital. Calculate the mean and standard deviation of the number of these patients who remained in the ICU for less than 24 hours. (C) Another result of the study was that for elective (non-emergency) admissions to the hospital's ICU, the length of the stay in the ICU had a mean of 18.9 hours and a standard deviation of 3.9 hours. Assuming that the length of stay in the ICU for elective admissions is normally distributed, what proportion of elective admissions remained in the ICU for less than 24 hours?
9) According to the American Academy of Ophthalmology, there is a 18% chance that someone will have hazel eyes. What is the probability that it will take at least seven people to find someone with hazel eyes?
