A table with one column labeled Response and another labeled Frequency. The first row says "0 Days" under response and 157 under Frequency. The next row reads "1 to 4 Days" under Response and 6191 under Frequency. Under Response, it reads "5 to 10 Days" and under Frequency, it reads 6819. It reads "11 to 14 Days" under Response and 12838 under Frequency. Lastly, it reads "Total" and then under Frequency, it says "26005."A bar graph with a horizontal axis labeled "Number of days" and a vertical axis labeled "Count" and numbered in increments of 5 thousand. For 0, the count is 15754. For 1, the count is 5061. For 2, the count is 5585. For 3, the count is 5094. For 4, the count is 2708. For 5, the count is 2388. For 6, the count is 1143. For 7, the count is 799.A bar chart labeled "Number of servings per day" on the horizontal axis and "Count" on the vertical axis, and numbered in increments of five thousand. For 0, the count is 6125. For 1-2, the count is 25290. For 3-4, the count is 6023. For 5-6, the count is 774. For more than 6, the count is 254.A bar chart with "M, Number of free throws made" on the horizontal axis and "Probability" on the vertical axis. For 0 and 1, the probability is 0.

For 7, the probability is 0.2265. For 8, the probability is 0.2977. For 9, the probability is 0.2318. For 10, the probability is 0.0812.A bar chart showing "C, Number of free throws made by Stephen Curry" on the x-axis and "Probability" on the y-axis. For 0 through 3, the probability is 0. For 4, the probability is 0.0001. For 5, the probability is 0.0011. For 6, the probability is 0.0087. For 7, the probability is 0.0487. For 8, the probability is 0.1783. For 9, the probability is 0.3863. For 10, the probability is 0.3768.A student napping on a desk in a classroom.A bar chart labeled "X, number of days that included a nap" on the horizontal axis" and "P(X)" on the vertical axis. For 0, P(X) is 0.361. For 1, P(X) is 0.195. For 2, P(X) is 0.165. For 3, P(X) is 0.107. For 4, P(X) is 0.058. For 5, P(X) is 0.045. For 6, P(X) is 0.023. For 7, P(X) is 0.045.A bar chart labeled "X, Number of Tails in Three Flips of a Coin" on the horizontal axis and "P(X)" on the y-axis. For 0, P(X) is 0.125. For 1, P(X) is 0.375. For 2, P(X) is 0.375. For 3, P(X) is 0.125.
