3. What is the probability of rolling a four in the gambling dice game of craps (given two six sided dice)? What is the probability that a player can roll a four 3 times in a row (assume that rolling the dice each time does not affect the outcome of the next roll)?
4. Population A and Population B both have a mean height of 60.0 inches with an SD of 5.0. A random sample of 40 people is picked from population A, and random sample of 30 people is selected from Population B. Which sample mean will probably yield a more accurate estimate of its population mean? Why? Calculate the Standard Error of the Mean (SEM) using the Central Limit Theorem, and explain how this equation supports your answer.
5. Suppose we obtained data on vein size after application of a nitroglycerin ointment in a sample of 60 patients. The mean vein size is found to be 8.4mm with an SD of 1.8. Using a t distribution table, what are the confidence limits for a 95% confidence interval? For a 99% confidence interval?

In the game of "Craps", a roller plays by rolling two six-sided dice. The score for each roll is the sum of the two dice. A roller can win on the first roll by rolling either a sum or 7 or 11. The probability of this occurring can be found using the sample space to be 0.2222. This probability (0.2222) is an example of what type of probability?
