SAT Test. In Exercises 15–20, assume that random guesses are made for eight multiple choice questions on an SAT test, so that there are n=8 trials, each with probability of success (correct) given by p=0.20. Find the indicated probability for the number of correct answers. Find the probability that the number x of correct answers is exactly 7.

Based on a survey, when 1009 consumers were asked if they are comfortable with drones delivering their purchases, 42% said yes. The probability of randomly selecting 30 of the 1009 consumers and getting exactly 24 who are comfortable with the drones is represented as 0+. What does 0+ indicate? Does 0 + indicate that it is impossible to get exactly 24 consumers who are comfortable with drones? Choose the correct answer below. O A. The probability 0+ indicates that the probability is a very small positive value. It indicates that the event is likely. O B. The probability 0+ indicates that the probability is a very small positive value. It indicates that the event is impossible. O C. The probability 0+ indicates that the probability is zero. It indicates that the event is impossible. O D. The probability 0+ indicates that the probability is a very small positive value. It indicates that the event is possible, but very unlikely.

Based on a survey, assume that 29% of consumers are comfortable having drones deliver their purchases. Suppose that we want to find the probability that when four consumers are randomly selected, exactly two of them are comfortable with delivery by drones. Identify the values of n, x, p, and q. 2 S d The value of n is (Type an integer or a decimal. Do not round.) The value of x is (Type an integer or a decimal. Do not round.) The value of pis (Type an integer or a decimal. Do not round.) W The value of q is (Type an integer or a decimal. Do not round.)

Jake tossed a paper cup 50 times and recorded how it landed. The table shows the results: Position Open Side Up Closed Side Up Landing on Side Number of Times Landed in Position 2 6 42 Based on the table, determine the experimental probability of each outcome (landing open side up, landing closed side up, and landing on its side). Show your work.

A students takes a 5 - question, multiple-choice exam with four choices for each question and guesses on each question. Find the probability of guessing exactly 2 out of 5 correctly. O 0.205 O 0.063 0.264 O None of these answers
