A random variable is uniformly distributed over[0,1].What is its skew?

Hi,

I've been moving in circles around this question for quite sometime now.

**I would appreciate it someone would be kind enough to provide me with the full answer and some explanation please. **

As you can see I've been provided with several leads and unfortunately I came up with some funny answer you can see in the post below by me with a similar heading.

I got sigma to be approximately 0.3 and cubed it to get 0.027

for E((x-1/2)^3=-0.5(using the equation above i.e integral)

**final answer was -18.5 ?? :?:** I 'm sure it is not correct
