30 ! 5 give ! 1. if you flip a coin 200 times, approximately how many times will it land heads up? 2. if you flip a coin 200 times and it lands heads up every time, what is the probability that it will land heads up on the next flip? 3. suppose you select a card at random from a standard deck of cards 60 times, and 12 of those selections are hearts. how does the experimental probability compare to the theoretical probability? include the difference between both types in your explanation. 4. determine if each of the following pairs of events is dependent or independent of each other: 1. flipping a coin, then rolling a die 2. drawing a card from a deck of 52 cards, then drawing a second card 3. rolling a die, then rolling a second die 4. spinning a game spinner twice 5. taking and eating a candy from a jar that contains equal amounts of cherry and orange candies, then taking a second candy. give an example of an event that is certain and an event that is impossible. what are the probabilities for each event? 5. thomas rolled a six sided die 100 times. he recorded his results as odd or even. the number of odds were 42 and the number of evens were 58. he thought he would get 50 heads and 50 tails. explain to thomas why the experimental probability may be different from the theoretical probability.

Name and describe the three most important measures of central tendency. choose the correct answer below. a. the mean, sample size, and mode are the most important measures of central tendency. the mean of a data set is the sum of the observations divided by the middle value in its ordered list. the sample size of a data set is the number of observations. the mode of a data set is its highest value in its ordered list. b. the sample size, median, and mode are the most important measures of central tendency. the sample size of a data set is the difference between the highest value and lowest value in its ordered list. the median of a data set is its most frequently occurring value. the mode of a data set is sum of the observations divided by the number of observations. c. the mean, median, and mode are the most important measures of central tendency. the mean of a data set is the product of the observations divided by the number of observations. the median of a data set is the lowest value in its ordered list. the mode of a data set is its least frequently occurring value. d. the mean, median, and mode are the most important measures of central tendency. the mean of a data set is its arithmetic average. the median of a data set is the middle value in its ordered list. the mode of a data set is its most frequently occurring value.
