Answer:

a. \frac{1}{36} 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:

p = (\frac{1}{6})^2 = \frac{1}{36}

a. What is the chance you win?

\frac{1}{36} 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

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

The expected value of the game is -$2.08.

Ludmilka [50]

Answer:

The method of separation is chromatography.

Step-by-step explanation:

It is given that a drawing of a circle made in the center of a piece of paper with a black marker gets wet, the marker bleeds, and as the water moves through the paper the ink separates into several colors. Here, the method of  separation used is chromatography. It is a laboratory technique for the separation of a mixture. When water or dye passes through a medium and changes color, then that means chromatography is used there.

4) You randomly select one card from a​ 52-card deck. Find the probability of selecting the 6 of hearts or the ace of diamonds.
MakcuM [25]

Answer:

1/26

Step-by-step explanation:

There is only one 6 of hearts and only one ace of diamonds.

The probability of selecting the 6 of hearts is thus 1/52, and that of selecting the ace of diamonds is also 1/52.

The probability of selecting the 6 of hearts or the ace of diamonds is the SUM of these two results:  1/52 + 1/52 = 2/52 = 1/26.

The point-slope form of a line that has a slope of –2 and passes through point (5, –2) is shown below.
Ilya [14]

Answer:

y =-2x+8

Step-by-step explanation:

We have a point and a slope

(5,-2)  and m =-2

The slope intercept form of a line is

y = mx+b

y = -2x+b

Substitute in the point

-2 = -2(5)+b

-2 = -10+b

Add 10 to each side

-2+ 10 = -10+10 +b

8 = b

The equation is

y =-2x+8
