Explanation / Answer
Total Students: 1000. (1) probability of Low Students rating = Low Rating students/ Total Students = 145/1000 = 0.145 (2) probability of rated excellent in terms of their nutritional status = Total Excellent Students /Total Students = 470/1000 =0.470 (3) probability of a low academic performance and an excellent nutrition status , = low academic performance and an excellent nutrition status Students / Total Students = 65/1000 =0.065 (4) Probability of Had low academic performance given that he or she had excellent nutritional status = low academic performance Students/ Total Excellent nutritional Students = 65/470 = 0.138 (5) Probability of Had high academic performance or excellent nutritional status. = Students high academic performance or excellent nutritional status /Total Students = = 550/1000= 0.550
