To find the probability that a business student is not enrolled in statistics, we need to subtract the number of students who are enrolled in statistics from the total number of business students:
1000 - 200 = 800
Next, we need to subtract the number of students who are enrolled in accounting but not statistics from the previous result:
800 - 250 = 550
Therefore, the probability that a business student selected at random is not enrolled in statistics is 550/1000 = 0.55, which is equivalent to 0.80 (since 1 - 0.55 = 0.45, and we know that the probability of being enrolled in statistics is 0.45). Thus, the best choice is D.
