A survey of eating habits showed that approximately 4% of people in a certain city are vegans. Vegars do not eat meat, poultry, fish, seafood, eggs, or milk. A restaurant in the city expects 400 people on opening night, and the chef is deciding on the menu. Treat the patrons as a simple random sample from the city and the surrounding area, which has a population of about 600,000. If 20 vegan meals are available, what is the approximate probability that there will not be enough vegan meals-that is, the probability that 21 or more vegans will come to the restaurant? Assume the vegans are independent and there are no families of vegans. The probability is (Round to three decimal places as needed)

In Wyoming, there are about 300,000 registered voters, of whom 30,000 are Democrats. A survey organization is about to take a simple random sample of 900 registered voters. The expected value for the percentage of Democrats in the sample is

There are four major types of​ blood: A,​ B, AB, and O. Suppose 42​% of a certain population has Type​ A, 9​% Type​ B, 6​% Type​ AB, and 43 % Type O blood. The blood type of a randomly selected person from this population is determined as part of an experiment. Complete parts a through b.   a. List the probabilities for each outcome in the sample space. Are they equally​ likely?   Select the correct choice below and fill in the answer​ box(es) to complete your choice. ​(Type integers or decimals. Do not​ round.)   A. Each outcome is equally​ likely; P(A)=​P(B)=​P(O)=enter your response here   B. Each outcome is equally​ likely; ​P(AB)=​P(AO)=​P(BO)= P(ABO)=enter your response here   C.

Five percent of all blue ray players manufactured by a large electronics company are defective. A quality control inspector randomly selects three players from the     production line. What is the probability that exactly one of these three blue ray players is defective?

A survey was done in regards to what type of animals are preferred as pets. Each respondent selected their top choice of animal for a pet. Respondents selected from: dog, cat, farret, fish, and bird.  After the survey was completed, 41% picked dog, 34% picked cat, 4% picked farret, 8% picked fish, and 13% picked bird.  Suppose three respondents were chosen at random. What is the probability that AT LEAST ONE of them picked dog?  Round the answer to 3 decimal places.

60% of all students at a college still need to take another math class. If 46 students are randomly selected, find the probability that a. Exactly 26 of them need to take another math class. b. At most 27 of them need to take another math class. C. At least 26 of them need to take another math class. d. Between 27 and 32 (including 27 and 32) of them need to take another math class.

A survey from Teenage Research Unlimited found that 40% of teenage consumers receive theirspending money from part-time jobs. If 5 teenagers are selected at random:a. Find the probability that at least 3 of them will have part-time jobs.b. Find the probability that no more than 4 will have part-time jobs.c. Find the probability that less than 5 but greater than 3 will have part-time jobs.

29% of all college students major in STEM (Science, Technology, Engineering, and Math). If 44 college students are randomly selected, find the probability that a. Exactly 10 of them major in STEM. b. At most 14 of them major in STEM. c. At least 12 of them major in STEM. d. Between 7 and 15 (including 7 and 15) of them major in STEM.
