On average, TV crash after 17,000 hours of continuous use. Although the time for the TV to crash is random, researchers have found that the duration until the computer crashes follows an exponential probability distribution. a. What is the probability that the TV will fail with a usage time of less than 17,000 hours?b. What is the probability that the TV will crash with a usage time of more than 17,000 hours?c. What is the probability that no TV will fail after more than 17,000 hours of use?d. What do you think about the results of points b and c above! What is the difference?
