The total number of business students enrolled in at least one of the courses is 200 (statistics only) + 250 (accounting only) + 50 (both courses) = 500. Therefore, 1000 - 500 = 500 students are not enrolled in either course. The probability is 500/1000 = 0.50 or 50%. However, the correct calculation leads to a 50% probability, which matches option B, not C. My initial statement was incorrect due to a misinterpretation of the final calculation. The correct answer, based on the calculation provided, should be B) 0.50, not C) 0.55.
