The owners of a two-person business make their decisions independently of each other and then compare their decisions. If they agree, the decision is made; if they do not agree, then further consideration is necessary before a decision is reached. If each has a history of making the right decision 60% of the time, what is the probability that together they:

a. Make the right decision on the first try

b. Make the wrong decision on the first try

c. Delay the decision for further study
