8.  There are 8 books in the “Statistics is Fun” series.  (Show all work. Just the answer, without supporting work, will receive no credit). (a) How many different ways can Mimi arrange the 8 books in her book shelf? (b) Mimi plans on bringing two of the eight books with her in a road trip. How many different ways can the two books be selected?  

 

7. Consider rolling two fair dice. Let A be the event that the sum of the two dice is 8, and B be the event that the first one lands on 6.  

(a) What is the probability that the first one lands on 6 given that the sum of the two dice is 8? Show all work. Just the answer, without supporting work, will receive no credit. (b) Are event A and event B independent? Explain.

10. Mimi plans on growing tomatoes in her garden. She has 15 cherry tomato seeds.  Based on her experience, the probability of a seed turning into a seedling is 0.40.  

(a) Let X be the number of seedlings that Mimi gets.  As we know, the distribution of X is a binomial probability distribution. What is the number of trials (n), probability of successes (p) and probability of failures (q), respectively?         (b) Find the probability that she gets at least 2 cherry tomato seedlings. (round the answer to 3 decimal places) Show all work. Just the answer, without supporting work, will receive no credit
