ive probability of green candies selected. (Source: Mars, Inc.) If it is, identify a success, specify the values of n, p, and q, and list the possible and 12, determine whether the experiment is a binomial experiment, values of the random variable x. If it is not a binomial experiment, explain why. selected from each of 12 bags. The random variable represents the number 11. Bags of milk chocolate M&M's contain 16% green candies. One candy is 12. A fair coin is tossed repeatedly until 15 heads are obtained. The random variable x counts the number of tosses. In Exercises 13-16, find the indicated binomial probabilities. If convenient, use technology or Table 2 in Appendix B. three. (Source: Gallup) want to lose weight is (a) exactly three, (b) at least three, and (c) 13. Fifty-three percent of U.S. adults want to lose weight. You randomly select eight U.S. adults. Find the probability that the number of U.S. adults who more than than two. (Source: Gallup) 14. Thirty-nine percent of U.S.…

A golf ball is selected at random from a golf bag. If the golf bag contains 4 brown ​balls, 6 orange ​balls, and 11 black ​balls, find the probability of the following event.   The golf ball is brown or orange.       Question content area bottom Part 1 The probability that the golf ball is brown or orange is enter your response here. ​(Type an integer or a decimal rounded to three decimal places as​ needed.)

Multiple-choice questions each have 3 possible answers, one of which is correct. Assume that you guess the answers to 5 such questions. Use the multiplication rule to find the probability that the first four guesses are wrong and the fifth is correct. That is, find P(WW WWC), where C denotes a correct answer and W denotes a wrong answer. (round answer to 4 decimal places) P(WWWWC) || What is the probability of getting exactly one correct answer when 5 guesses are made? (round answer to 4 decimal places) P(exactly one correct answer) = %3D

determine whether the random variable X has a binomial distribution.  If it does state the number of trials n.  If it does not, explain why not. Twenty students are randomly chosen from a math class of 70 students.  Let X be the total number of student absences. Part 1 The random variable -does -does not have a binomial distribution   Part 2 Choose the statement that explains why X does not have a binomial distribution, more than one may apply -The Number of trials is not fixed -There are more than two possible outcomes for each trial -The probability of success is not the same for each trial -The trials are not independent -X does not represent the number of successes that occur
