Solution
We first note that the same number can appear more than once and up to three times.
The possible combinations are:
Now,
(1) can be arranged in 3 ways, like (1, 6, 6), (6, 1, 6) or (6, 6, 1)
(2) can be arranged in 6 ways, like (2, 5, 6), (2, 6, 5), (5, 2, 6), (5, 6, 2), (6, 2, 5) or (6, 5, 2)
(3) can be arranged in 6 ways, like (3, 4, 6), (3, 6, 4), (4, 6, 3), (4, 3, 6), (6, 4, 3)or (6, 3, 4)
(4) can be arranged in 3 ways, like (3, 5, 5), (5, 5, 3) or (5, 3, 5)
(5) can be arranged in 3 ways, like (4, 4, 5), (4, 5, 4) or (5, 4, 4).
Thus, in total, the possible combinations are: (3 x 3) + (2 x 6)
= 21 Answer

Part I - Throwing a Dice with Six Faces (32 points) Consider a dice with six faces, i.e. a standard dice. The possible outcomes after throwing the dice once are 1, 2,3, 4,5,6 (a) Assume that the dice is thrown once. Let w represents the outcome. Explain why P(w-i) for i = i..6, when the dice is fair (b) The fair dice is thrown twice. Find the probability of occurance of at least one 6 The fair dice is thrown...
Write a program which implements a dice game. Name your program file 'YourUsernameA105.py, e.g. afer023A1Q5.py. The aim of the game is to reach a score as close as possible to 100 (but not over 100) in three rounds. Each round consists of throwing five random dice, the user then chooses two of the dice values where the two dice values chosen form a two digit score which is added to the user's current total, e.g., if the user first chooses...
For the two six-sided dice case: Write out the six-by-six matrix showing all possible (36) combinations of outcomes. Draw a histogram of the probability of outcomes for the dice totals. Explain the shape of the histogram. Draw a Venn diagram for the 36 dice roll combinations. Define a set "A" as all the combinations that total seven; define set "B" as all the combinations that have one die roll (either die 1 or 2) equal to 2. Indicate the sets...

( Java Programming ) Write an application to simulate the rolling of two dice. The application should use an object of class Random once to roll the first die and again to roll the second die. The sum of the two values should then be calculated. Each die can show an integer value from 1 to 6, so the sum of the values will vary from 2 to 12, with 7 being the most frequent sum, and 2 and 12...
