question 1-14 on section 7.5
Question 1 3 pts Trafc engineers are investigating the high rate of fatal accidents at a lighted city intersection. They discover that 7 % of the cars that are within 200 feet of the intersection when the light turns red pass through the red light without stopping. Suppose two cars are now within 200 feet of the intersection and the light turns red. Assuming that drivers behave independently of one another, What is the probability that both drivers pass through the red light without stopping? (Please do not round your answer). Question 2 3 pts Given P (A) =0.452 what is the probability of complement, Z , of the event? In other words, what is POI) :1? Note: Enter your answer in the box below without rounding it. Question 3 3 pts Given P(E) =0.416 , P(F) =0.359 , P(E U F) =0.65 , what is the value of P (E n F) 2? Note: Enter your answer in the box below without rounding it. E Question 4 3 pts The Chicago Bears football team has a probability of 0.52 to win the next game, and a probability of 0.19 to tie the next game. What is the probability for the team to lose the next game? Note: Please enter your nal answer in full without rounding it. E Question 5 3 pts Determine the probability of event E if the odds against E are 26 to 29. Note:For any final answer that has up to four decimal places, enter your answer without rounding the number. For any answers with more than four decimal values, round your final answer to four decimal places. Question 6 3 pts Determine the probability of event E if the odds for (i.e., in favor of) E are 20 to 15. Note:For any final answer that has up to four decimal places, enter your answer without rounding the number. For any answers with more than four decimal values, round your final answer to four decimal places.Question 7 3 pts In the days he was still playing, Reggie Miller could score from the free-throw line 93 % of the time. Suppose he is playing in a game and he is fouled and has got to shoot two. Assuming that the result of each free-throw is independent of the result of the other free-throw, What is the probability that he will score at least one of the shots? Note: Please enter your answer in the box below without rounding it. Question 8 3 pts Traffic engineers are investigating the high rate of fatal accidents at a lighted city intersection. They discover that 23 % of the cars that are within 200 feet of the intersection when the light turns red pass through the red light without stopping. Suppose two cars are now within 200 feet of the intersection and the light turns red. Assuming that drivers behave independently of one another, What is the probability that at least one of the drivers passes through the red light without stopping? (Please do not round your answer). Question 9 3 pts Given P(E) 20.413 , P(F) 20.321 , P(E n F) 20.072 , what is the value of P (E U F) 2? Note: Enter your answer in the box below without rounding it. Question 10 3 pts Anne is taking courses in both mathematics and English. She estimates her probability of passing mathematics at 0.42 and passing English at 0.48 , and she estimates her probability of passing at least one of the courses at 0.73 . What is the probability that Anne could pass both courses? Note: Enter your nal answer in the box below without rounding it.

Note:For any final answer that has up to four decimal places, enter your answer without rounding the number. For any answers with more than four decimal values, round your final answer to four decimal places. Question 12 3 pts Given, P (E) =0.101 , P(EUF) =0.376 , P(En F) =0.083 , what is P (F) =? Note: Enter your answer in the box below without rounding it.Question 13 3 pts Determine the probability of event E if the odds_against E are 9 to 12. NotezFor any final answer that has up to four decimal places, enter your answer without rounding the number. For any answers with more than four decimal values, round your nai answer to four decimal places. 2 Question 14 3 pts Suppose events A and B are mutually exclusive events in sample space S.
