Strategic Practice and Homework Problems. Actively solving practice problems is essential for learning probability. Strategic practice problems are organized by concept, to test and reinforce understanding of that concept. Homework problems usually do not say which concepts are involved, and often require combining several concepts. Using both however, the textbook and the exercise book, the mathematical statistician will enjoy the wealth of interesting problems."

Sum of remaining 5 numbers = 15 × 5 = 75. Number removed = sum of original 6 numbers – sum of remaining 5 numbers. Number removed = 120 – 75 = 45. Alternative Method: Let x be the removed number. The removed number is 45. Example: 10 students of a class had a mean score of 70. …
