In a gambling game, you roll 2 die and if you toss 2 sixes, you win $100, otherwise you lose $5.
a. What is the chance you win?
b. What is the expected value of the game?

Answers

Answer 1

Answer:

a. [tex]\frac{1}{36}[/tex] chance you win.

b. The expected value of the game is -$2.08.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

You roll 2 die and if you toss 2 sixes

For each roll, 6 possible values, 1 of which is 6. So the probability of rolling two sixes is:

[tex]p = (\frac{1}{6})^2 = \frac{1}{36}[/tex]

a. What is the chance you win?

[tex]\frac{1}{36}[/tex] chance you win.

b. What is the expected value of the game?

1/36 probability of winning 100.

35/36 probability of losing 5. So

[tex]E = \frac{1}{36}*100 - \frac{35}{36}*5 = \frac{100 - 175}{36} = -\frac{75}{36} = -2.08[/tex]

The expected value of the game is -$2.08.

Answer:

Step-by-step explanation:

Hi,

3/4 divided by 1/2 is the same thing as 3/4 x 2/1. (when dividing fractions, flip the second fraction) When you do this, you simply multiply straight across. So...

3/4 x 2/1 = 6/4

Simplify...

3/2 (both 6 and 4 can be divided by 2)

3/2 = 1 1/2

Answers

Answer:

x = 20

Step-by-step explanation:

since the triangle is a right angle, that means the angle is 90 degrees

equation:

30 + 3x = 90

subtract 30 on both sides

30 - 30 + 3x = 90 - 30

3x = 60

then divide each side by 3

[tex]\frac{3x}{3} = \frac{60}{3}[/tex]

x = 20

A television is discounted 20% in a sale. A shopper has a coupon for an additional 15% off the sale price. Which of the following is the total percent discount from the original price of the television?

Answers

The total is 35% off of the original price.

Step by step explanation:

If the television is discounted by 20% in a sale and the shopper also has a coupon for an additional 15% of the sale price than you just add up the percentages and that’s the total percent of the discount.

I hope this helped you understand! :)

The total percent discount arises from the real price of the television is 32%.

Given that,

The television should be discounted at 20% in the sale i.e. price after discount should be 0.80 of the real price There is an additional 15% off the sale price. So, 15% of 80% i.e. 12%.

So, the total percent discount should be

= 20% + 12%

= 32%

Therefore we can conclude that The total percent discount arises from the real price of the television is 32%.
