This question asks for a fraction, a reduced fraction, and a mixed number. 2 Enter fractions like 2/3 for. For this type, the 2 fraction does not need to be reduced, so is 4 1 considered the same as For a reduced fraction answer, be sure to reduce 1 your fraction to lowest terms. If = is the correct 2 2 answer, is not reduced, and would be marked 4 wrong. For both fraction and reduced fraction type 10 problems,...

Lesson 3 Simultions 1. A small opinion poll. Suppose that 90% of a university's students favor abolishing evening exams. You as 10 students chosen at random. What is the probability that all 10 favor abolishing evening exams? (a) Give a probability model for asking 10 students independently of each other. yes = 0.90 NO- 0.10 (b) Assign digits to represent the answers "Yes" and ves=0-7 NO=8-9 (c) Simulate 25 repetitions of asking 10 students, starting at line 129 of Table...
