How to use the Random Generator calculator?

• Select the generator type from the drop-down list.
• Uniform integer: Generate whole numbers between your set minimum and maximum.
• Uniform decimal: Generates random decimal values between your set minimum and maximum.
• Normal distribution: Generates values based on a bell curve using a mean and standard deviation.
• Random from list: Picks one or more items from your custom list (e.g., names, tasks).
• Dice roll: Simulates rolling dice with your chosen number of dice and sides per die.
• Coin flip: Flips a virtual coin, giving “heads” or “tails”.
• Lottery number: Generates a random set of lottery numbers within your given range.
• Enter the lowest and maximum values: Specify the decimal or number range.
• Enter the number of values: Decide how many random outcomes you require.
• Enter the standard deviation and mean: For the results of a normal distribution, enter the mean and standard deviation.
• Put in a custom list: Put items in with commas between them.
• Enter the number of sides and dice for each die: To simulate a dice roll, enter the number of dice and sides per die.
• Lottery minimum and maximum numbers: Define the lottery draw number.
• Numbers to pick: Choose how many numbers to generate.
• After entering the values, click “Calculate”, and in seconds, you will see the result.

Examples

Uniform integer

Generate 10 random integers from 5 to 25? Min = 5, Max = 25, Number of values = 10

• Step 1: Uniform Integer Random Generation
• Step 2: Range: 5 to 25
• Step 3: Count: 10
• Generated numbers: 24, 9, 23, 18, 21, 11, 20, 14, 9, 11
• Numbers: 24,9,23,18,21,11,20,14,9,11
• Statistics: [object Object]

Uniform decimal

Min = 0, Max = 1, Number of values = 2

• Range: 0 to 1
• Count: 2
• Generated numbers: 0.216757, 0.071386
• Result: 0.216757, 0.071386

Normal Distribution

An instructor wants to follow the test scores of 10 students, hoping for an average of 50 and a standard deviation of 5. Mean= 50 Standard Deviation= 5 Number of Values= 10

Dice roll

Number of dice = 2, side of per die = 6, Number of Values=2

• Number of dice: 2
• Sides per die: 6
• Individual rolls: 5, 3
• Total: 8
• Average per_die: 4

Lottery number

Number of values=1, standard deviation=1, number of dice=1, sides per dice=6, Lottery Min Number=1, Lottery Max Number=49, numbers to pick = 2

• Step 1: Lottery Number Generation
• Step 2: Range: 1 to 49
• Step 3: Numbers to pick: 2
• Step 4: Selected numbers: 32, 42
• Step 5: Odds of winning: 1 in 1,176
• Lottery numbers: 32,42
• Odds: 1 in 1,176

• Double-check your minimum and maximum values.

FAQ

Can I make more than one random number at the same time?

Yes, enter a number in the "number of values" box, and the calculator will give you more than one answer right away.

How does the choice for normal distribution work?

Random numbers around the mean are generated by it. It is controlled by the standard deviation, which measures how spread out the numbers are.

Can I use this calculator for games?

Yes! You can use it to roll dice, flip coins, or pick random things for fair game play.
