2) There are many methods to make crooked dice. To load die so that 6 comes up too often and 1 (which is opposite 6) comes up too seldom, add bit of lead to filling of the spot on 1 face. As the spot is solid plastic, this works even with transparent dice. If die is loaded so that 6 comes up with probability 0.2 and probabilities of 2,3,4, and 5 faces are not affected, determine the assignment of probabilities to the six faces?
