=RAND()
The RAND function can be used to generate a random number between 0 and 1. For example, using this formula will generate a random number. This value will always be greater than or equal to 0, and less than 1.
=RAND()*(9-1)+1
The RAND function can also be used to generate random numbers between lower and upper bounds. For example, if you want a random number between 1 and 9 you can use the above formula. This is calculated by taking the random number between 0 and 1, multiplying it by the difference between the upper and lower limits (9 - 1 = 8), and then adding the lower limit (1).
The RAND function returns an evenly distributed random real number between 0 and 1.
