A game has 3 possible outcomes, with probabilities p1, p2, and p3. The amount of money that you will win or lose for each outcom

Monica [59]

We have the following given
p1 - probability for outcome 1
p2 - probability for outcome 2
p3 - probability for outcome 3
v1 - amount of money that you will win or lose for outcome 1
v2 - amount of money that you will win or lose for outcome 2
v3 - amount of money that you will win or lose for outcome 3

Therefore,
p1v1 + p2v2 + p3v3 is the average money you win or lose in playing the game.

<u>Answer:</u>

The correct answer option is D. $\frac { 3 n ^ { 3 } } { 5 m ^ { 2 } }$ .

<u>Step-by-step explanation:</u>

We are given the following expression and we are to simplify it:

$\frac { 3 m ^ { - 2 } } { 5 n ^ { - 3 } }$

Here the variables $m$ and $n$ are having negative powers. So to change these powers from negative to positive, we will take their reciprocals to get:

$\frac { 3 n ^ { 3 } } { 5 m ^ { 2 } }$
