A construction company employs 2 executive engineers, Engineer I does the work for 60% of jobs of the company. Engineer 2 does the work for 40% of jobs of the company. It is known from the past experience that the probability of an error when engineer does the work is 0.03, whereas the probability of an error in the work of engineer 2 is 0.04. Suppose a serious error occurs in the work, which engineer would you guess did the work?
