Hoping to increase the chances of reaching a performance goal, the director of a research project has assigned 4 separate research teams the same task with the same specifications. The director estimates that the team reliabilities for successfully completing the task in the allotted time are 0.90, 0.80, 0.70, and 0.60. Assuming that all the teams work independently, what is the probability that the task will be completed by at least one of them in time?
