Density function for continuous random variables

  1. Sep 26, 2011 #1
    For the density function for random variable Y:
    f(y) = cy^2 for 0<= y <= 2; 0 elsewhere
    We are asked to find the value of c. I did a definite integral from 0 to 2 of cy^2. I get c = 3/8. Why would the book show an answer of c = 1/8? Is this an error on their part or am I missing something stupid?

    Indeed, I also think it's an error in the book.
