### Probability04

1. 1. February 26, 2009 Long Night True or False probability
2. 2. February 26, 2009 HOMEWORK Design an experiment to determine the probability of passing a six-question multiple choice test if you guess all the answers. Each question has four answers, and one answer is correct in each case. How many simulations would seem reasonable? What is the experimental probability of getting at least 50% on the test?
3. 3. February 26, 2009 HOMEWORK Design an experiment using coins to simulate a 10 question true/false test. What is the experimental probability of scoring at least 70% on the test if you guess each answer?
4. 4. February 26, 2009 Design an experiment using coins to simulate a 10 question true/false test. What is the experimental probability of scoring at least 70% on the test if you guess each answer? randBin(# of trials, probability of success, # of experiments) How would you use your calculator to answer this question? On the calculator ... Press: [MATH] [<] (Prb) [7] (randBin) How would you use Random.org to answer this question? http://www.random.org/
5. 5. February 26, 2009 Find the probability of flipping three pennies and getting at least 1 heads.
