If you are limited to polyhedral dice, then no. They do sell “D3” dice, but they are six-sided, with two sides showing each number between 1 and 3. Similarly, you could make a D5 using a ten-sided polyhedron.
Can a die have an odd number of sides?
For the addition question, let’s look at the regular dice. It has three even sides and three odd sides, so it has a 50% change of rolling even and a 50% chance of rolling odd. … If the three add to an even number, there’s a 50% chance that the regular dice will be odd and make the sum odd.
What is the probability of rolling a 4 or an odd number?
There are two cases, one where you first get the four, or you get an odd then a four. The probability of just rolling a 4 first is 16. If you roll one odd number before the 4, that has a chance of 12∗16 Now, you can roll 2 or 6 infinitely many times and it won’t matter.
What is the probability of rolling a 3 or an odd number?
In this situation, rolling a six-sided has 6 outcomes, each of which is equally likely, so we can define the probability of an event (such as rolling a 3 or rolling an odd number) as the ratio of favorable outcomes to possible outcomes: the probability of rolling a 3 is 16 and the probability of rolling an odd number …
What is the probability of getting an odd or a prime number when rolling a die?
The odd prime numbers that could appear on a die roll are 3 and 5 (note that 1 is not considered a prime). Since theer are 6 possible roll outcomes, the probability of an odd prime is 2 out of 6 or 2/6=1/3.
What is P roll an even number?
The probability of rolling an even number is three out of six, or three-sixths. This fraction can be simplified as the numerator and denominator are both divisible by three. Three divided by three is equal to one, and six divided by three is equal to two. This means that the answer, in its simplest form, is one-half.
What is opposite 6 on a dice?
On a standard 6 sided die the numbers on opposite sides add up to 7. Therefore the number opposite 6 is 1.
