An experiment consists of testing 10 units for a specified period of time. The probability of the unit failure in a test is 0.1. The experiment is considered a success if 8 or more units survive the time period. a) What is the probability that the experiment will be failed? b) If the experiment will be repeated 5 times, what is the probability that at least 3 times experiments will be successful?
