Use the CDF method to find the following pdfs.

- ) Let X~ Uniform(0,1) and let Y= -10ln(X). Find the pdf of Y. What kind of RV is Y? (Tip: Watch out for that "-")
- ) Let X~ Normal(0,1) and let Y = e^x. What is

the paf of Y? (Hint: this is called a Log-Normal Distribution)

c.) Let X~ Exponential(A = 1/3) and let Y= X1/2

What is the pdf of Y? (Hint: this is called a

Weibull Distribution)
