Problem 1
What is the probability of an event that is impossible? Suppose that a probability is approximated to be zero based on empirical results. Does this mean the event is impossible?
Problem 2
What method of assigning probabilities to a simple event uses relative frequencies?
Problem 3
True or False: In a combination problem, order is not important.
Problem 3
True or False: In a probability model, the sum of the probabilities of all outcomes must equal 1 .
Problem 4
Suppose that you roll a pair of dice 1000 times and get seven 350 times. Based on these results, what is the probability that the next roll results in seven?
Problem 4
What does it mean when two events are complements? In Problems \(5-12,\) a probability experiment is conducted in which the sample space of the experiment is \(S=\\{1,2,3,4,5,6,7,8,9,\) 10,11,12\\}\(.\) Let event \(E=\\{2,3,4,5,6,7\\},\) event \(F=\\{5,6,7,8,9\\},\) event \(G=\\{9,10,11,12\\},\) and event \(H=\\{2,3,4\\} .\) Assume that each outcome is equally likely.
Problem 4
True or False: Probability is a measure of the likelihood of a random phenomenon or chance behavior.
Problem 5
Let the sample space be \(S=\\{1,2,3,4,5,6,7,8,9,10\\} .\) Suppose that the outcomes are equally likely. Compute the probability of the event: \(E=\\{1,3,5,10\\}\)
Problem 7
Determine whether the events \(E\) and \(F\) are independent or dependent. Justify your answer. (a) \(E:\) Speeding on the interstate. \(F:\) Being pulled over by a police officer. (b) \(E:\) You gain weight. \(F:\) You eat fast food for dinner every night. (c) \(E\) : You get a high score on a statistics exam. \(F:\) The Boston Red Sox win a baseball game.
