Expected value of max and min

Let $X_1,X_2,...,X_n$ be IID random variables with uniform distribution between $0$ and $1$.
What are the cumulative distribution function, the probability density function and expected value of $Z =\max(X_1,X_2,...,X_n)$? What are the cumulative distribution function, the probability density function and expected value of $Y = \min(X_1,X_2,...,X_n)$?
Compute $E[Z-Y]$ for $n=11$ (this is the value to enter).
