Transcribed Image Text:Most cohiputer 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 a denote a random number generated using RAND, then a is a continuous random variable with the
following probability density function.
1 for 0<a<1
0 e lsewhere
f(x) =
a. Select the probability density function.
