Quizplus · Accepted Answer

The probability of selecting a maintenance employee can be found by dividing the number of maintenance employees by the total number of employees. 
Probability of selecting a maintenance employee = (25/100) = 0.25 
However, the question asks for the probability of selecting the first person classified as a maintenance employee, so we need to adjust the probability for the first selection: 
Probability of selecting a maintenance employee on the first selection = (25/100) * (1/1) = 0.25 
Therefore, the probability that the first person selected is classified as a maintenance employee is 0.25 or 0.025 (if expressed as a decimal). 
So, the answer is option C.
