please circle the answers

i just need the answers

make sure i understand what are you write

thank you

You wake up from a nightmare in which you've completely forgotten about the final exam in your stats class. Since you haven't studied, you estimate that there is an 80% chance of answering any individual problem correctly. Determine the chance that you answer a problem incorrectly. Choose the correct answer below. O A. 80% O B. 20% O C. There is not enough information.A computer can be classified as either cutting-edge or ancient. Suppose that 94% of computers are classified as ancient. (a) Two computers are chosen at random. What is the probability that both computers are ancient? (b) Five computers are chosen at random. What is the probability that all five computers are ancient? (c) What is the probability that at least one of five randomly selected computers is cutting-edge? Would it be unusual that at least one of five randomly selected computers is cutting-edge? (a) Two computers are chosen at random. What is the probability that both computers are ancient? The probability is (Round to four decimal places as needed.) (b) Five computers are chosen at random. What is the probability that all five computers are ancient? The probability is. (Round to four decimal places as needed.) (c) What is the probability that at least one of five randomly selected computers is cutting-edge? The probability is. (Round to four decimal places as needed.) Would it be unusual that at least one of five randomly selected computers is cutting-edge? It would that at least one of five randomly selected computers is cutting-edge. be unusual not be unusualA university conducted a survey of 390 undergraduate students regarding satisfaction with student government. Results of the survey are shown in the table by class rank. Complete parts (a) through (d) below. Click the icon to view the table. (a) If a survey participant is selected at random, what is the probability that he or she is satisfied with student government? - X P(satisfied) = Data table (Round to three decimal places as needed.) b) If a survey participant is selected at random, what is the probability that he or she is a junior? Freshman Sophomore Junior Senior Total P(junior) = Satisfied 57 46 67 59 229 Neutral 28 18 13 14 73 (Round to three decimal places as needed.) Not satisfied 22 18 19 29 88 (c) If a survey participant is selected at random, what is the probability that he or she is satisfied and a junior? Total 107 82 102 390 P(satisfied and junior) = (Round to three decimal places as needed.) (d) If a survey participant is selected at random, what is the probability that he or she is satisfied or a junior? P(satisfied or junior) = (Round to three decimal places as needed.) Print DoneA golf ball is selected at random from a golf bag. If the golf bag contains 7 yellow balls, 5 orange balls, and 9 brown balls, nd the probability of the following event. The golf ball is yellow or orange. E> The probability that the golf ball is yellow or orange is (Type an integer or a decimal rounded to three decimal places as needed.) Next question Is the following a probability model? What do we call the outcome "blue"? Color Probability red 0.1 green 0.25 blue 0 brown 0.35 yellow 0.25 orange 0. 1 Is the table above an example of a probability model? O A. No, because the probabilities do not sum to 1. O B. Yes, because the probabilities sum to 1 and they are all greater than or equal to 0 and less than or equal to 1. O C. Yes, because the probabilities sum to 1. O D. No, because not all the probabilities are greater than 0. What do we call the outcome "blue"? O A. Impossible event O B. Unusual event O C. Certain event O D. Not so unusual event
