K In a certain state, it has been shown that only 69% of the high school graduates who are capable of college work actually enroll in college. Find the probability that, among 9 capable high school graduates in this state, 4 to 6 inclusive will enroll in college. The probability that, among 9 capable high school graduates in this state, from 4 through 6 will enroll in college is 0.684 (Round to three decimal places as needed.)

Assume that when adults with smartphones are randomly selected, 52% use them in meetings or classes. If 25 adult smartphone users are randomly selected, find the probability that exactly 19 of them use their smartphones in meetings or classes. The probability is. (Round to four decimal places as needed.)

None

Assume that when adults with smartphones are randomly selected, 39% use them in meetings or classes. If 15 adult smartphone users are randomly selected, find the probability that exactly 9 of them use their smartphones in meetings or classes. The probability is (Round to four decimal places as needed.)

Assume that when adults with smartphones are randomly selected, 53% use them in meetings or classes. If 10 adult smartphone users are randomly selected, find the probability that at least 3 of them use their smartphones in meetings or classes. The probability is 0.0905 (Round to four decimal places as needed.)

Assume that when adults with smartphones are randomly selected, 54% use them in meetings or classes. If 10 adult smartphone users are randomly selected, find the probability that at least 8 of them use their smartphones in meetings or classes. The probability is. (Round to four decimal places as needed.)

A vaccine has a 87% probability of being effective in preventing disease. The probability of getting the disease if a person is not vaccinated is 46%. In a certain geographic region, 21% of the people get vaccinated. If a person is selected at random, find the probability that he or she will contract the disease. Round your answer to three decimal places. Also, draw a tree diagram or a table to support your work.

33% of all college students major in STEM (Science, Technology, Engineering, and Math). If 38 college students are randomly selected, find the probability that a. Exactly 11 of them major in STEM. b. At most 11 of them major in STEM. c. At least 14 of them major in STEM. d. Between 10 and 15 (including 10 and 15) of them major in STEM. Round all answers to 4 decimal places.
