Answer:

Expected Value = -1$

Step-by-step explanation:

Expected Value: So, expected value is the very important concept of probability, from insurance to governments, from casinos to lotteries the concept of expected value is used. It is basically the expected gain or loss when you perform the task repeatedly.

So here’s the question statement:

Bet = 3$  

Bet is on: Number 3 of a 6 faced dice.

Total numbers on dice = 6 = Total number of outcomes

Bet is on how many numbers = 1 = Number of Favorable outcomes.

If you win: you will get:     12$ = 3$ (Bet amount) + 9$ (outcome)

Outcome of winning = 9$

Probability of winning = Favorable outcome divided by Total number of outcomes = 1/6 = 0.16666..

If you lose you will lose:   3$ (Bet amount)

Outcome of losing = -3$ ( - “minus” represents losing)

Probability of losing = Favorable outcome divided by Total number of outcomes = 5/6 = 0.8333…

So, expected value is calculated when you play this game repeatedly right?

Formula to calculate Expected Value:

Expected Value = (Outcome of Winning) x (Probability of Winning) + (Outcome of Losing) x (Probability of Losing)

So, we have all these variables. Now just put values into the equation of expected value.  

Expected Value =  (9$) x (1/6) + (-3$) x (5/6)

Expected Value = -1$  

It means, every time you play the game you are expected to lose 1$.

Answer: See below

Step-by-step explanation:

The transformation from triangle LMN to triangle L'M'N' is the reflection about the line y =x.

The line segment from L to y=x and the line segment from L' to line y=x are congruent.

Yes, we will get the same characteristic if we draw a line from point M to y=x and the line  from M' to y=x.

It is because points P', M' and N' are reflections of points P, M, and N respectively about the line y=x.

Graph 1 (attached as first picture)

Graphing a triangle LMN and reflecting it over the line y = x to create triangle L'M'N, we have:

The transformation from triangle LMN to triangle L'M'N' is the reflection about the line y =x.

Drawing a line from point L to the line y=x and from line L' to line y=x we have:

Graph 2 (attached as second picture)

The line segment from L to y=x and the line segment from L' to line y=x are congruent.

Yes, we will get the same characteristic if we draw a line from point M to y=x and the line  from M' to y=x.

It is because points P', M' and N' are reflections of points P, M, and N respectively about the line y=x.
