Choice (c) is correct. Since each number is equally likely to be chosen so, the sample space has 100 (equally likely) sample points. Following are the 10 favourable sample points or outcomes: 9, 18, 27, 36, 45, 54, 63, 72, 81, 90 Thus, the required probability = 10/100 = 1/10 This question relatedRead more
