What is Dice: Definition and 228 Discussions

Dice (singular die or dice) are small, throwable objects with marked sides that can rest in multiple positions. They are used for generating random numbers, commonly as part of tabletop games, including dice games, board games, role-playing games, and games of chance.
A traditional die is a cube with each of its six faces marked with a different number of dots (pips) from one to six. When thrown or rolled, the die comes to rest showing a random integer from one to six on its upper surface, with each value being equally likely. Dice may also have polyhedral or irregular shapes and may have faces marked with numerals or symbols instead of pips. Loaded dice are designed to favor some results over others for cheating or entertainment.

    What is the angle of a hanging dice during acceleration?

    Homework Statement A pair of fuzzy dice is hanging by a string from your rearview mirror. While you are accelerating from a stoplight to 29 m/s in 5.7 s, what angle θ does the string make with the vertical? Homework Equations v_f=v_0+a*t x_f=x_0+v_0*t+0.5a*t^2 v_f^2=v_0^2+2*a(x_f-x_0)...

    Dice problem that I can't fully get my head around

    There's a probability question I saw on the web that looks innocent enough, unless you pay attention to the wording: I have two dice. If i roll them until i get a double, which is the most likely roll to get a double on? The answer given is below: The first roll is the most likely. Heres...

    What is the probability of scoring a sum of 7 after 20 tosses with 2 dice?

    Suppose we make 20 tosses using 2 dice. What is the probability of scoring a two numbers that sum to 7? My attempt The sample space for a single toss of a single die is S = {1, 2, 3, 4, 5, 6} For a single toss of both dice, the sample space is S = {(1, 1), (1, 2), (1, 3), (1, 4), (1...

    Conditional probability - Random number of dice

    Can someone help me with this question ? A random number N of dice is thrown. Let Ai be the event that N = i, and assume that P(Ai) = 1/(2)^i, i >= 1. The sum of the scores is S. Find the probability that: (a) S = 4, given N is even; (b) the largest number shown by any die is r, where S...

    Probability of Rolling Sum > 8 w/ Dice: Calculating Probability & Avg Rolls

    A pair of dice is being rolled. The probability for rolling a sum greater than 8 is 10/36. Is the probability for it taking two rolls to attain a sum greater than 8 just 26/36 times 26/36? I need to make a table of the number of rolls it takes to obtain a sum greater than 8, and the...

    Slicing dice and cutting corners

    A dice has 6 sides. If you cut the corners of a dice you get 6 + 8 = 14 sides. If you cut again, the minimum number of sides you get is 6 + 8 + 12. If you cut n times, what is the minimum number of sides you get?

    Probability of Throwing at least 1 "6" vs Double 6 in Dice Rolls

    TASK: Show that throwing at least one "6" within 4 throws of a die is more likely than throwing a "double 6" within 24 throws of two dice. SOLUTION: I can do the first result two ways. Firstly, I can use the complement of "four dice all showing something other than six" which would be 1 -...

    Calculating Probability of Rolling a 7 with Dice

    The probability of rolling a 7 with a pair of ordinary dice is 1/6 because, of the 36 possible (and equally likely) combinations, six of them sum to 7. Now, suppose the dice are rolled out of one's sight and some honest person who can see the result tells us that at least one of the dice came up...

    Roll of the Dice: Number Probability

    Curious, since dice have varying indentations per side(one, two, three, four, five, six), is a dice(die?) not more apt to settle with the single "one spot" down on the table?
