Numbers surround us from birth and play an important role in life. For many people, the work itself is connected with numbers, someone relies on luck, filling lottery tickets with numbers, and someone gives them a completely mystical meaning. One way or another, sometimes we cannot do without using a program such as random number generator.
For example, you need to organize a prize draw among the subscribers of your group. Our online random number generator will help you choose winners quickly and honestly. You just need, for example, to set the desired number of random numbers (by the number of winners) and the maximum range (by the number of participants, if they are assigned numbers). Fraud in this case is completely excluded.
This program can also serve as a random number generator for lotto. For example, you bought a ticket and want to completely rely on chance and luck in choosing numbers. Then our number randomizer will help fill your lottery ticket.

The random number generator, which is presented on our website, is very convenient. For example, it can be used in drawings and lotteries to determine the winner. Winners are determined in this way: the program gives out one or more numbers in any range you specify. The manipulation of the results can be immediately eliminated. And thanks to this, the winner is determined in a fair choice.
Sometimes you need to get a certain number of random numbers at once. For example, you want to fill out a “4 out of 35” lottery ticket, trusting in chance. You can check: if you toss a coin 32 times, what is the probability that 10 reverses will fall out in a row (heads / tails may well be assigned by the numbers 0 and 1)?

For example, you have a Vkontakte group. In a group, you are drawing 5 prizes, among the number of participants who repost the entry. With the help of a special application, we received a list of participants. Each was assigned a serial number for numbers online.
Now we go to our online generator and indicate the range of numbers (number of participants). For example, we ask that 5 numbers are needed online, since we have 5 prizes. Now we press the generate button. Then we get 5 random numbers online, in the range from 1 to 112 inclusive. The generated 5 numbers online will correspond to the serial number of the five participants who became the winners of the draw. Everything is simple and convenient.
Another plus of the random number generator is that all online numbers are randomly generated. That is, it is not possible to influence it, or to calculate what number will be next.

We have a sequence of numbers, consisting of almost independent elements that obey a given distribution. Usually evenly distributed.
You can generate random numbers in Excel in different ways and ways. Let's take a look at the best of them.
Random Number Function in Excel
- The RAND function returns a random uniformly distributed real number. It will be less than 1, greater than or equal to 0.
- The RANDBETWEEN function returns a random integer.
Let's look at their use with examples.
Selecting random numbers with RAND
This function does not require any arguments (RAND()).
To generate a random real number between 1 and 5, for example, use the following formula: =RAND()*(5-1)+1.
The returned random number is evenly distributed over the interval .
Each time the worksheet is calculated, or the value in any cell in the worksheet changes, a new random number is returned. If you want to save the generated population, you can replace the formula with its value.
- We click on a cell with a random number.
- Highlight the formula in the formula bar.
- Press F9. AND ENTER.
Let's check the uniformity of the distribution of random numbers from the first sample using the distribution histogram.
The range of vertical values is frequency. Horizontal - "pockets".
RANDBETWEEN function
The syntax of the RANDBETWEEN function is (lower bound; upper bound). The first argument must be less than the second. Otherwise, the function will throw an error. The bounds are assumed to be integers. The formula discards the fractional part.
An example of using the function:
Random numbers with 0.1 and 0.01 precision:
How to make a random number generator in Excel
Let's make a random number generator with the generation of a value from a certain range. We use a formula like: =INDEX(A1:A10;INTEGER(RAND()*10)+1).
Let's make a random number generator in the range from 0 to 100 with a step of 10.
From the list of text values, you need to select 2 random ones. Using the RAND function, we compare text values in the range A1:A7 with random numbers.
Let's use the INDEX function to select two random text values from the original list.
To select one random value from the list, apply the following formula: =INDEX(A1:A7,RANDBETWEEN(1,COUNT(A1:A7))).
Normal Distribution Random Number Generator
The functions RAND and RANDBETWEEN produce random numbers with a single distribution. Any value with the same probability can fall into the lower limit of the requested range and into the upper one. It turns out a huge spread from the target value.
Normal distribution means that most of the generated numbers are close to the target. Let's correct the RANDBETWEEN formula and create a data array with a normal distribution.
The cost of goods X is 100 rubles. The entire batch produced is subject to a normal distribution. The random variable also follows a normal probability distribution.
Under such conditions, the average value of the range is 100 rubles. Let's generate an array and build a graph with a normal distribution with a standard deviation of 1.5 rubles.
We use the function: =NORMINV(RAND();100;1.5).
Excel calculated which values are in the range of probabilities. Since the probability of producing a product with a cost of 100 rubles is maximum, the formula shows values close to 100 more often than the rest.
Let's move on to plotting. First you need to create a table with categories. To do this, we divide the array into periods:
Based on the data obtained, we can form a diagram with a normal distribution. The value axis is the number of variables in the interval, the category axis is the periods.
