What is the formula to generate random numbers?
If we wish to generate a random number between two numbers, we can use the formula: RAND() * (b – a) + a, where a is the smallest number and b is the largest number that we wish to generate a random number for.
How do I generate a random number in Salesforce?

Method 1: Using Math.random() function: The Math.random() function is used to return a floating-point pseudo-random number between range [0,1) , 0 (inclusive) and 1 (exclusive). This random number can then be scaled according to the desired range. Syntax: Math.random();
How do you generate random numbers with mean and standard deviation?
Formula Syntax Use the formula “=NORMINV(RAND(),B2,C2)”, where the RAND() function creates your probability, B2 provides your mean and C2 references your standard deviation. You can change B2 and C2 to reference different cells or enter the values into the formula itself.
Can Excel generate random names?

How to generate a random array of integers?
At the core of this formula is the RANDARRAY function that creates a random array of integers, with the value in C2 defining how many values to generate. The minimal number is hardcoded (1) and the maximum number corresponds to the number of rows in your data set, which is returned by the ROWS function.
