For each probability and percentile problem, draw the picture.The speed of cars passing through the intersection of Blossom Hill Road and the Almaden Expressway varies from 10 to 35 mph and is uniformly distributed. None of the cars travel over 35 mph through the intersection. State "P(20 < X < 51) = ___" in a probability question. What is the probability that the speed of a car is below 20 or above 51 mph? What is the probability that the speed of a car is below 20 given that it is below 51 mph? What is the probability that the speed of a car is between 20 and 51 mph? What is the probability that the speed of a car is exactly 20 or 51 mph? Draw the picture and find the probability. (Enter your answer as a fraction.)
A dental clinic wants to properly handle their walk-in and appointment customers. According to the assistant's daily data collection of last year's activity, the probability distribution for x (the number of walk-in customers per day) is as shown in the table.

No; the probability of all events in the table is not greater than or equal to 0 and less than or equal to 1. O B. No; the sum of the probabilities of all outcomes does not equal 1. OC. No: the probability of all events in the table is not greater than or equal to 0 and less than or equal to 1, and the sum of the probabilities of all outcomes does not equal 1. OD. Yes; the rules required for a probability model are both met.
Allen Abbott has a wide-curving, uphill driveway leading to his garage. When there is a heavy snow, Allen hires a local carpenter, who shovels snow on the side in the winter, to shovel his driveway. The snow shoveler charges $30 to shovel the driveway. Following is a probability distribution of the number of heavy snows each winter: Heavy Snows Probability 1 .13 2 .18 4 .26 5 .23 6 .10 7 .07 .03 1.00 Allen is considering purchasing a new self-propelled snowblower for $625 that would allow him, his wife, or his children to clear the driveway after a snow. Discuss what you think Allen’s decision should be and why.

How many cups-o-joe do you drink? About 72% of Americans drink coffee. How much they drink: 1 cup a day 27% 2 or more cups a day 45% 2 cups 1 сup a week a week 15% 13% Source: Braun Research for International Delight Coffee House Inspirations Use the information in this display to answer the following questions. Assume that the percentages in the graph are representative of adult Americans. (a) What is the probability that a randomly selected adult American drinks coffee? (b) The display associates 13% with the category "one cup of coffee a week." For the chance experiment that consists of selecting an adult American at random, is 0.13 the probability that the selected individual drinks one cup of coffee a week, or is it the conditional probability that the selected individual drinks one cup of coffee a week given that he or she drinks coffee? Explain. O This is the probability that the selected individual drinks one cup of coffee a week, because that probability is less than 72%,…
