Question

Find the specified probability.
-Use the special addition rule and the following probability distribution to determine $\mathrm { P } ( 6 < X \leq 8 )$.
$\begin{array}{cccccccc}
\mathrm{X} & 5 & 6 & 7 & 8 & 9 & 10 & 11 \
\hline \mathrm{P}(\mathrm{X}=\mathrm{x}) & 0.05 & 0.05 & 0.20 & 0.15 & 0.15 & 0.10 & 0.30
\end{array}$
A)$1.00$
B) $0.35$
C) $0.40$
D) $0.45$

Quizplus · Accepted Answer

The probability $ P(6 < X \leq 8) $ is found by adding the probabilities of $ X = 7 $ and $ X = 8 $, which are $ 0.20 + 0.15 = 0.35 $.
