Excel RAND Function. Most computer languages include a function that can be used to generate random numbers. In Excel, the RAND function can be used to generate random numbers between 0 and 1 . If we let x denote a random number generated using RAND, then x is a continuous random variable with the following probability density function. f(x)={ 1 for 0 ≤ x ≤ 1 0 elsewhere. a. Graph the probability density function. b. What is the probability of generating a random number between
