In the casino game chuck-a-luck, three fair six-sided dice are rolled, and their outcomes are independent. the player loses $1 if no fives are rolled. the player wins $1 for each five that is rolled. let x be a random variable denoting the amount of money won or lost by the player during one round of this game. the possible values of x are -1, 1, 2, or 3. (hint: consider the three events e1 that the first die shows a five, e2 that the second die shows a five, and e3 that the third die shows a five. notice these events are mutually independent.)

Im literally having a mental breakdown

The customer price index(cpi), which measures the cost of a typical package of customer goods, was 208.8 in 2011 and 244.1 in 2016.let x=11 corresponding to the year 2011 an estimate to cpi into 2013 and 2014. assume that the data can be modeled by a straight line and the trend to continue idenfinitely. use data points to find such a line and then estimate the requested quantities

If your score on your next statistics test is converted to a z score, which of these z scores would you prefer: minus2.00, minus1.00, 0, 1.00, 2.00? why? a. the z score of 2.00 is most preferable because it is 2.00 standard deviations above the mean and would correspond to the highest of the five different possible test scores. b. the z score of 0 is most preferable because it corresponds to a test score equal to the mean. c. the z score of minus2.00 is most preferable because it is 2.00 standard deviations below the mean and would correspond to the highest of the five different possible test scores. d. the z score of minus1.00 is most preferable because it is 1.00 standard deviation below the mean and would correspond to an above average
