A constructor has two subcontractors for his excavation work. Experience shows that in 60% of ne time, subcontractor A was available to do a job, whereas subcontractor B was available 80% f the time. Also, the contractor is able to get at least one of these two subcontractors 90% of the me. a. What is the probability that both subcontractors will be available to do the next job b. If the contractor learned that subcontractor A is not available for the job, what is the probability that the other subcontractor will be available c. Suppose Ea denotes the event that subcontractor A is available, and Es denotes that subcontractor B is available. i. Are Es and En statistically independent? Explain ii. Are Ea and Es mutually exhaustive? Explain iii. Are Es and Es collectively exhaustive? Explain
