2013年4月30日 · A four sided die is a tetrahedron, so it lands with a vertex pointing up, not with a face pointing up. The problem is that you cannot paint a number on a vertex, only on a face, right? So there are two solutions. You can treat the upward-facing vertex as the outcome of the roll, and label it by printing a number close to the vertex.

Make a probability distribution for the given set of events : The sums that appear when two fair four-sided dice (tetrahedrons) with sides 2, 4, 6 and 8 are tossed Complete the probability distribution below.

You have a bag with three fair dice. One is 4-sided, one is 6-sided, and one is 12-sided. You reach into the bag, pick one die at random, and roll it. The outcome of the roll is 4. What is the probability that you rolled the 6-sided die?

A 4-sided die can be used to select a number randomly from the numbers 1, 2, 3, and 4. Suppose you roll a 4-sided die along with an 8-sided die. a) Draw a diagram of the sample space for rolling these two dice. b) How many possible outcomes are there? c) Find the probability of rolling 'double'. That is the event of getting the same number …

There is little demand for these kinds of dice from my knowledge. Another way you could do roll dice to save money and to get the same results is to just roll a d8 and do 1-2=1, 3-4=2, 5-6=3, and 7-8=4.

2017年6月16日 · There also exist "eight sided" and "twelve sided" dice that are numbered 1-4 multiple times (twice or thrice respectively). Even though they have more than four sides, they generate an even distribution between 1 and 4, so they are still d4s.

Roll a pair of four-sided dice, one red and one black, each of which has possible outcomes 1, 2, 3, 4 that have equal probabilities. Let X equal the outcome on the red die, and let Y equal the outcome on the black die.

If you roll two four-sided dice (numbered 1, 2, 3, and 4), what is the probability that the sum of the dice is 8? You roll 3 6-sided dice. What is the probability that the three dice will total more than 6? Suppose that the number of dice thrown is a binomial random variable with n = 25 and p = 0.42 .

A ten-sided dice, numbered 1 to 10, is rolled. Calculate the probability that the number rolled is a multiple of 3 or a multiple of 4.

You have a pair of 4-sided dice. The four sides of each die are numbered 1, 2, 3, and 4. Each time the pair of dice is rolled, you add the numbers from each die. A) Out of all the possible ways the dice can land, how many of them give you a sum of 7? B) How many ways give you a sum of 4? C) What is the probability of rolling a sum of 5 with these dice?
