Rainbow [258]

Answer:

$11

Step-by-step explanation:

$\left\begin{array}{c|ccc}&$Lose \$25&$Gain \$5&$Gain \$45\\$Stock ABC&40\%&15\%&45\%\end{array}\right$

We want to calculate the expected gain or loss of Stock ABC with the probabilities above.

Note that loss is written in negative.

$E$xpected Value =$ (-25 \times 40\%)+(5 \times 15\%) + (45 \times 45\%)\\=(-25 \times 0.4)+(5 \times 0.15)+(45 \times 0.45)\\=-10+0.75+20.25\\=\$11$

Stock ABC has an expected gain of $11.
