A standard roulette wheel has 38 numbered slots for a small ball to land in: 36 are marked from 1 to 36, with half of those blac
Anastasy [175]

Answer:

The expected value of betting $500 on red is $463.7.

Step-by-step explanation:

There is not a fair game. This can be demostrated by the expected value of betting a sum of money on red, for example.

The expected value is calculated as:

E(G)=\sum p_iG_i

being G the profit of each possible result.

If we bet $500, the possible outcomes are:

- <em>Winning</em>. We get G_w=$1,000. This happens when the roulette's ball falls in a red place. The probability of this can be calculated dividing the red slots (half of 36) by the total slots (38) of the roulette:

P(R)=R/T=18/38\approx0.4737  

- <em>Losing</em>. We get G_l=$0.  This happens when the ball does not fall in a red place. The probability of this is the complementary of winning, so we have:

P(not \,R)=1-P(R)=1-18/38=20/38\approx 0.5263

Then,  we can calculate the expected value as:

E(G)=\sum p_iG_i=p_wG_w+p_lG_l=0.4637*1,000+0.5263*0=463.7

We expect to win $463.7 for every $500 we bet on red, so we are losing in average $36.3 per $500 bet.

If 2x and 120? are the pair of co-interior angle find the value​
Pachacha [2.7K]

Answer:

2x + 120 = 180 (being co interior angle)

or, 2x = 180 - 120

or, 2x = 60

or, x = 60/2

or, x = 30

therefore 2x = 2* x = 2* 30= 60

Which of the following ordered pairs represents the solution to the system given below?
tigry1 [53]

Answer:

The solution to the system would be (3, -1)

Step-by-step explanation:

You can find the solution to this system by using the elimination method. To do that, start by multiplying the top equation by -5 and then adding it through.

-5x + 20y = -35

5x + 9y = 6

-----------------

29y = -29

y = -1

Now that we have the value of y, we can plug it into either equation and find the x value.

x - 4y = 7

x - 4(-1) = 7

x + 4 = 7

x = 3
