![Let \( x \) be a hypergeometric random variable with \( N = 12 \), \( n = 3 \), and \( M = 5 \).
Use the formulas given below to calculate \( \mu = E(x) \) and \( \sigma^2 \). (Round your answer for \( \sigma^2 \) to five decimal places.)
\[
\mu = n \left( \frac{M}{N} \right)
\]
\[
\sigma^2 = n \left( \frac{M}{N} \right) \left( \frac{N - M}{N} \right) \left( \frac{N - n}{N - 1} \right)
