Probabilities of this Dice Roller

Probability of getting atleast one 1 is close to 1., about 100% 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 - (0/1 x 0/1 x 0/1 x 0/1)

Probability of not getting any 1 is close to 0., about 0.% percent.

This is calculated by multiplying all the probabilities of not getting a 1 for each dice.

0/1 x 0/1 x 0/1 x 0/1

Probability of getting all 1's is close to 1., about 100% percent.

This is calculated by multiplying together all the probabilities of getting a 1 for each dice.

1/1 x 1/1 x 1/1 x 1/1

Probability of getting 4 1's is close to 1., about 100% percent.

This is calculated by multiplying together all the probabilities of getting a 1 for each dice that has a 1.

1/1 x 1/1 x 1/1 x 1/1

Probability of getting all the maximum faces (4 1's) is close to 1., about 100% percent.

This is calculated by multiplying together all the probabilities of getting the maximum face for each dice.

1/1 x 1/1 x 1/1 x 1/1

Probability of getting one of a kind is close to 1., about 100% percent.

There are 1 ways to get one of a kind (all 1's). The probability of getting all of any kind is then caclulated by adding the probability of getting all 1's. Since, probabilities of getting all 1's through all 1's are the same, we can multiply them all together. So, multiplying the probability of getting all 1's by 1 will give us the probability of getting all of any kind.

Javascript code to create this dice roller


    
                   
        // define the range of numbers to pick from
        var lowest = 1;             // lowest possible side of the dice
        var highest = 1;           // highest possible side of the dice
        var numbers_of_dice = 4;    // how many dice to roll     
        
        var this_roll = []; // array to store the results of this roll

        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 dice array 

            //print each dice roll value followed by a space
            document.write(this_roll[j]);
