Question

Jorge wants to draw a conclusion about the possible expected values of rolling a 2 on a standard die for different numbers of roll. Jorge can conclude that an even number of rolls

Answer 1

may result in an expected value that is even, odd, or a decimal. The expected value is equal to the product of the theoretical probability of rolling a 2 on 1 die roll, or 1/6, and the number of die rolls. A total of 300 rolls gives an expected value of 50, which is even. A total of 200 rolls gives an expected value of 33.3, which is a repeating decimal. A total of 30 rolls gives an expected value of 5, which is odd.
