A 5-column table with 4 rows. The columns are labeled sock 2 and the rows are labeled sock 1. Column 1 contains entries blank, b, b, w, w. Column 2 contains entries b, (b, b), (b, b), (w, b), (w, b). Column 3 contains entries b, (b, b), (b, b), (w, b), (w, b). Column 4 contains entries w, (b, w), (b, w), (w, w), (w, w). Column 5 contains entries w, (b, w), (b, w), (w, w), (w, w).
A drawer contains one pair of brown socks and one pair of white socks. The table shows the possible outcomes, or sample space, for choosing a sock, replacing it, and then choosing another sock.

If the first sock is not replaced, how many possible outcomes are there?

How many of these outcomes contain a matching pair of socks?

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.
