In a recent poll, 50 teenagers were asked do they exercise regularly. 35% of them said they do exercise regularly. 9. What is the random variable? 10. What is the probability that 35 teenagers said yes? 11. What is the probability that 20 teenagers said yes? 12. What is the probability that between 16 and 19 teenagers said yes? Binomial Probability Main Assignment Complete this assignment and use it to complete the daily check associated with the lesson. Binomial or Not? Determine whether each experiment is a binomial experiment. If the scenario is binomial, list the 2 outcomes. If it is not binomial, explain why not. 1. You survey 25 students to find out how many are left-handed. The random variable represents the number of left-handed people. 2. You roll a die 110 times to see if a 5 appears. The random variable represents the number of 5's. 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. A kindergarten class has 20 children. The probability that any child has Type O blood is 0.25. 5. What is the random variable? 6. What is the probability that exactly 7 students have Type O blood? 7. What is the probability that 4 students have Type O blood? 8. What is the probability that at most 2 students have Type O blood?
