    A die means a standard cube whose faces are numbered 1, ..., 6 and each has equal probability of being rolled. A green die and a red die are rolled simultaneously, with equal probability for each of the 36 possible outcomes. Describe the sample space. Then find the probability that: a. the sum is 7; b the sum is 11; thesumis7or11; thesumisneither7nor11; b. the same value occurs on each die; c. the value on the green die is greater than...

    4. [20 Points We first examine a sequence of rolls of a four-sided die at an the observed outcome Xi E {1,2,3,4}. At each of these times, the casino can be in one of two states z E1, 2}. When z = 1 the casino uses a fair die, while when z = 2 the die is biased so that rolling a 1 is more simple hidden Markov model (HMM). We observe a "occasionally dishonest casino", where at time likely....
