A contractor is planning the acquisition of construction equipment, including bulldozers, needed for a new project in a remote area. Suppose that from his prior experience with similar bulldozers, he estimated that there is a 65% chance that each bulldozer can remain operational for at least 6 months. 1.) If he purchased four bulldozers for the new project, what is the probability that there will be at least two bulldozers left operational after six months into the project?.
