    You roll a 6-sided die. The die has one to six spots on each side, with each count (1, 2, 3, 4, 5, or 6) appearing once. The die is fair: each side has an equal chance that it will be up when the die lands. What is the probability that you will roll a value greater than or equal to 2? Express your answer in decimal form to 3 decimal places.

    1. A standard six-sided die has a different number from 1 through 6 on each side, with thoe average roll being a 3.5. Grime dice, on the other hand, have a different set of numbers of each side, with the same average roll as shown in the table. In this problem (or generally unless otherwise stated), we treat the dice as fair, such that any side is likely to be the top face when rolled Die Normal Red Grime Side...
