A process has a probability of defectives of np = 8. What is the probability of finding exactly 3 defectives in a sample? 2.86% 28.6% 286% O None of theseive 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.
