Step 1
Given: x: 0, 1, 2 P(x): 0.15, 0.30, 0.55 Expected value (mean) = Σ(x * P(x)) Expected value = (0 * 0.15) + (1 * 0.30) + (2 * 0.55) Expected value = 0 + 0.30 + 1.10 Expected value = 1.40 Show more…

Determine the missing probability value for the probability distribution. $$\begin{array}{|l|l|l|l|l|l|l|l|} \hline \boldsymbol{x} & 0 & 1 & 2 & 3 & 4 & 5 & 6 \\ \hline \boldsymbol{P}(\boldsymbol{x}) & 0.5 & ? & 0.23 & 0.21 & 0.17 & 0.11 & 0.08 \\ \hline \end{array}$$
