Question

If 1 toss a fair coin five times and the outcomes are T???? (i.e. 5 tails in a row), then the probability that tails appears on the next toss is a) less than 0.5. b) greater than 0.5. c) 0.5. d) 0 e) 1 The probability of an outcome of a random phenomenon is a) either 0 or 1, depending on whether or not the phenomenon can actually occur. b) the proportion of a very long series of repetitions on which the outcome occurs. c) the mean plus or minus two standard deviations. d) another name for its expected value. e) the confidence level. 6. As the number of tosses of a fair coin goes up from 10, to 100, to 1000, and to 10,000, what happens to the probability of getting between 40% and 60% heads? a) The probability increases. b) The probability decreases. c) The probability does not change. d) We don't know until we toss the coin. A multiple choice exam offers 5 choices for each exam. Jason just guesses the answers, so he has a probability of 1/5 of getting any one answer correct. One of your math major friends tells you that the probability model for the number of questions you get right on the entire exam is (entries rounded to three decimal places): What is the probability that Jason gets more than zero answers correct? a) 0.108 b) 0.268 c) 0.500 d) 0.628 e) 0.892
