What Excel function is used for selecting a random input value X between 0 and 1?

• A. RAND()
• B. NORM.INV()
• C. NORM.DIST()
• D. RANDBETWEEN()

Answer: (B)

The function that correctly selects a random input value X between 0 and 1 in Excel is the function that generates a random number uniformly distributed in that range. The function RAND() is designed specifically for this purpose. It returns a random decimal number greater than or equal to 0 and less than 1. NORM.INV() is not applicable in this context, as it is used to return the inverse of the normal distribution for a specified mean and standard deviation, and it is not designed to generate random variables uniformly. NORM.DIST() also is meant for calculating the normal distribution probabilities and does not generate random numbers. RANDBETWEEN() generates a random integer between two specified values, but not a decimal value between 0 and 1. Therefore, the correct function for generating a random value between 0 and 1 is RAND(), which fits the requirement of the question perfectly.
