In a Box of 7 Batteries,3 Are Dead $$\begin{array} { l | c c c } \text { Number good } & 0 & 1 & 2 \\\hline \mathrm { P } \text { (Number good) } & 0.184 & 0.490 & 0.327\end{array}$$

In a box of 7 batteries,3 are dead.You choose two batteries at random from the box.Let the random variable X be the number of good batteries you get.Find the probability model for X.

A) $$\begin{array} { l | c c c } \text { Number good } & 0 & 1 & 2 \\\hline \mathrm { P } \text { (Number good) } & 0.184 & 0.490 & 0.327\end{array}$$
B) $$\begin{array} { l | c c c } \text { Number good } & 0 & 1 & 2 \\\hline \mathrm { P } \text { (Number good) } & 0.143 & 0.571 & 0.286\end{array}$$
C) $$\begin{array} { l | c c c } \text { Number good } & 0 & 1 & 2 \\\hline \mathrm { P } \text { (Number good) } & 0.143 & 0.286 & 0.286\end{array}$$
D) $$\begin{array} { l | c c c } \text { Number good } & 0 & 1 & 2 \\\hline \mathrm { P } \text { (Number good) } & 0.286 & 0.571 & 0.286\end{array}$$
E) $$\begin{array} { l | c c c } \text { Number good } & 0 & 1 & 2 \\\hline \mathrm { P } \text { (Number good) } & 0.067 & 0.467 & 0.467\end{array}$$
