Roll a D120 die and a D4 die
D120 + D4 Dice Roller
- Rolls a D120 die and a D4 die.
- Lets you roll multiple dice like 2 D120s, or 3 D120s. Add, remove or set numbers of dice to roll.
- Combine with other types of dice (like D118 and D122) to throw and make a custom dice roll.

Probabilities of this Dice Roller
Probability of getting atleast one 1 is close to 0.26, about 25.63% percent.
This is calculated by multiplying all the probabilities of not getting a 1 for each dice and then subtracting the answer from 1.
1 - (119/120 x 3/4)
Probability of not getting any 1 is close to 0.74, about 74.38% percent.
This is calculated by multiplying all the probabilities of not getting a 1 for each dice.
119/120 x 3/4
Probability of getting all 1's is close to 0.0021, about 0.21% percent.
This is calculated by multiplying together all the probabilities of getting a 1 for each dice.
1/120 x 1/4
Probability of getting 2 1's is close to 0.0021, about 0.21% percent.
This is calculated by multiplying together all the probabilities of getting a 1 for each dice that has a 1.
1/120 x 1/4
Probability of getting atleast one 4 is close to 0.26, about 25.63% percent.
This is calculated by multiplying all the probabilities of not getting a 4 for each dice and then subtracting the answer from 1.
1 - (119/120 x 3/4)
Probability of not getting any 4 is close to 0.74, about 74.38% percent.
This is calculated by multiplying all the probabilities of not getting a 4 for each dice.
119/120 x 3/4
Probability of getting all 4's is close to 0.0021, about 0.21% percent.
This is calculated by multiplying together all the probabilities of getting a 4 for each dice.
1/120 x 1/4
Probability of getting 2 4's is close to 0.0021, about 0.21% percent.
This is calculated by multiplying together all the probabilities of getting a 4 for each dice that has a 4.
1/120 x 1/4
Probability of getting atleast one 5 is close to 0.0083, about 0.83% percent.
This is calculated by multiplying all the probabilities of not getting a 5 for each dice and then subtracting the answer from 1.
1 - (119/120 x 4/4)
Probability of not getting any 5 is close to 0.99, about 99.17% percent.
This is calculated by multiplying all the probabilities of not getting a 5 for each dice.
119/120 x 4/4
Probability of getting all 5's is close to 0., about 0.% percent.
This is calculated by multiplying together all the probabilities of getting a 5 for each dice.
1/120 x 0/4
Probability of getting 1 5's is close to 0.0083, about 0.83% percent.
This is calculated by multiplying together all the probabilities of getting a 5 for each dice that has a 5.
1/120
Probability of getting atleast one 120 is close to 0.0083, about 0.83% percent.
This is calculated by multiplying all the probabilities of not getting a 120 for each dice and then subtracting the answer from 1.
1 - (119/120 x 4/4)
Probability of not getting any 120 is close to 0.99, about 99.17% percent.
This is calculated by multiplying all the probabilities of not getting a 120 for each dice.
119/120 x 4/4
Probability of getting all 120's is close to 0., about 0.% percent.
This is calculated by multiplying together all the probabilities of getting a 120 for each dice.
1/120 x 0/4
Probability of getting 1 120's is close to 0.0083, about 0.83% percent.
This is calculated by multiplying together all the probabilities of getting a 120 for each dice that has a 120.
1/120
Probability of getting all the maximum faces (a 120 and a 4) is close to 0.0021, about 0.21% percent.
This is calculated by multiplying together all the probabilities of getting the maximum face for each dice.
1/120 x 1/4
Probability of getting one of a kind is close to 0.0083, about 0.83% percent.
There are 4 ways to get one of a kind (all 1's, all 2's, all 3's or all 4's). The probability of getting all of any kind is then caclulated by adding the probability of getting all 1's, all 2's, all 3's or all 4's. Since, probabilities of getting all 1's through all 4's are the same, we can multiply them all together. So, multiplying the probability of getting all 1's by 4 will give us the probability of getting all of any kind.

Javascript code to create this dice roller
// define the sets of dice to use
// 1 set for each kind of dice
var dice_sets = [
[1, 120], // 1d120
[1, 4], // 1d4
];
var this_roll = []; // array to store the results of this roll
for (var ds = 0; ds < dice_sets.length; ds++) {
//loop through each dice set
// for each dice set, determine the numbers of dice, lowest and highest side of the dice
var numbers_of_dice = dice_sets[ds][0]; // how many dice to roll
var lowest = 1; // lowest possible side of the dice
var highest = dice_sets[ds][1]; // highest possible side of the dice
for (var j = 1; j <= numbers_of_dice; j++) {
// loop for the number of dice
// for each dice, generate a number between lowest and highest
var dice_face = Math.floor(Math.random() * (highest-lowest+1) + lowest);
this_roll.push(dice_face); //store this in the array
}
}
// print all the generated rolls
for (j = 0; j < this_roll.length; j++) {
// loop through the inner dice array
//print each dice roll value followed by a space
document.write(this_roll[j]);
document.write(" ");
}
