One season, the average little league baseball game averaged 2 hours and 53 minutes (173 minutes) to complete. Assume the length of games follows the normal distribution with a standard deviation of 11 minutes. Complete parts a through d below. a. What is the probability that a randomly selected game will be completed in less than 190 minutes? The probability that a randomly selected game will be completed in less than 190 minutes is 0.9389 (Round to four decimal places as needed.) b. What is the probability that a randomly selected game will be completed in more than 190 minutes? The probability that a randomly selected game will be completed in more than 190 minutes is 0.0611 (Round to four decimal places as needed.) c. What is the probability that a randomly selected game will be completed in exaqtly 190 minutes? The probability that a randomly selected game will be completed in exactly 190 minutes is (Round to four decimal places as needed.)
