Calculate the Expected Value of X for the Given Probability $$\begin{array} { c c c c c c c } x & - 20 & - 10 & 0 & 10 & 20 & 30 \\P ( X = x ) & 0.1 & 0.1 & 0.1 & 0.1 & 0.1 & 0.5\end{array}$$

question 66

Multiple Choice

Calculate the expected value of X for the given probability distribution: $$\begin{array} { c c c c c c c } x & - 20 & - 10 & 0 & 10 & 20 & 30 \\P ( X = x ) & 0.1 & 0.1 & 0.1 & 0.1 & 0.1 & 0.5\end{array}$$ Round your answer to two decimal places if necessary.

• A) \(E ( X ) = 14.79\)
• B) \(E ( X ) = 14.87\)
• C) \(E ( X ) = 14\)
• D) \(E ( X ) = 15.1\)
• E) \(E ( X ) = 15\)
