The probability that a printing press will print a book with no errors is 78%. The company is about to process an order of 30 books. Round decimals to 3 places or percentages to 1 decimal place. 9. What is the probability that the press printed exactly 12 books with no errors? 10. What is the probability that the press printed 22 books with no errors? 11. What is the probability that the press printed at least 27 books with no errors? 12. What is the probability that the press printed no more than 15 books with no errors? A manufacturer of halogen bulbs knows that 23% of the production of their 100W bulbs will be defective. Consider a carton of 6 bulbs. Round decimals to 3 places or percentages to 1 decimal place. 13. Calculate and create a probability distribution to model the random variable in this situation. 14. What is the probability that at most 2 bulbs in the carton 15. Is it more likely to have 0 or 5 defective bulbs in the will be defective? carton? Why? 16. What is the probability of having between 3 and 6 defective bulbs in the carton (inclusive)? 17. In a carton of 6 bulbs, how many can you expect to be defective? Binomial Probability Activity Main Assignment Complete this assignment and the submit your completed work to the dropbox associated with the lesson. Binomial or not? Determine whether each experiment is a binomial experiment. If an event is binomial, there are only two possible outcomes. If the scenario is binomial, list the 2 outcomes. Scenario 1. You survey 25 students to find out how many are left-handed. The random variable represent the number of left-handed people. 2. You roll a die 10 times to see if a 5 appears. The random variable represents the number of 5s. 3. You ask 15 people how old they are. The random variable represents their age. 4. You select 10 cards from a deck without replacement. The random variable represents the number of hearts. Choose One binomial not binomial binomial not binomial binomial not binomial binomial not binomial Possible Outcomes (if binomial) n = number of trials Binomial Probability Formula p = probability of success ncr pr qn-r r = number of successes qprobability of failure. also = 1-p Must have independent trials with only 2 outcomes, labelled success & failure. In a recent poll, 50 teenagers were asked do they exercise regularly. 35% of them said they do exercise regularly. Round decimals to 3 places or percentages to 1 decimal place. 5. What is the random variable? 7. What is the probability that 25 teenagers said yes? 6. What is the probability that 15 teenagers said yes? 8. What is the probability that 20 teenagers said yes?
