A computer engineer sequentially performs three maintenance operations on a server. - In 73% of maintenance, it performs operation A first.- 37 % is the percentage corresponding to the completion of operation B in second place, knowing that the execution of B was preceded by the execution of operation A.- Operation C is performed in third place in 27% of the maintenances in which operations A and B are performed in first and second, respectively. What is the probability that the engineer performed operations A and B first and second (respectively) and did not perform operation C third, in a randomly selected maintenance?
